Yoggi has a different style of riding than Kris. I've seen them both.
Where Yoggi does switch to seat out only if necessary, Kris switches to
seat in only if necessary 🙂
Kris doesn't drop from 3 metres, and Yoggi doesn't care that much
(about anything, heh).
I'd say they're both strong, yet I prefer KH.

I have heart that both bended on little drops, but I think this can
happen with every hub if the rider land a drop hard.

Kris has done high drops with his hub and Yoggi to, but Kris lands the
drops very smooth and controlled, Yoggi does 3m drops but I never has
see him landing one. I think you could not really say which hub is
better but I personally would prefer the KH.

I preffer the koxx one because of the cranks, they have no q-factor and
no knubs, so it doesnt hurt you knees.

Also the cranks are squared so you can grind better!!!

There was a thread like this a while ago, which compared the KH and the
Profile and involved the Koxx. The problem is that no one has subjected
both hubs to an objective test. However, in the earlier thread, Roger
(Davies, the head honcho at unicycle.com in Britain) made the point
that the fundamental design of the KH hub (which he helped design,
IIRC) makes it the strongest hub available. I would tend to believe
him.

What about a crank could hurt your knees? Does the q-factor have to do
with how far the pedals are from the wheel? Like |: :| as opposed to \:

Alright, cool. Which fundaments was he talking about? The Koxx-one
interface is tapered, and that is supposed to limit the eventual
noise/shifting.

Alright, here to set the record straight, is 'the thread is was
referring to' (http://tinyurl.com/abmll). It is a thread comparing
Profiles and Koxxes, but Roger brings up the KH/Onza hub (which he
helped design), and states that it is the strongest hub currently in
production (and light, too). Enter Kris, who explains the motivation
for developing said hub, and the KH rims, too. It's a great read, and I
would definitely bow to Roger's and Kris' superior knowledge, and
publicly say that the KH/Onza hubs are the best. Not that I use it, as
I've got the '04 Kris Holm with the older-generation hub. However, my
friend halfbike has that hub on his 20" Onza trials, and loves it
(which he shows by stomping around on it and generally subjecting it to
all kinds of abuse). Pretty dang strong.

The weigh is almost the same and the same happends with the strength.

So yo can choose just the one that has the shape that you like more. I
like the koxx because it has no knubs, no q factor and more surface for
grinding. other people has other opinions, this is mine.

If you are going really hard you should buy a profile because you would
like your stuff to be guarranted. If not you can buy any splined set
you want!!

Never heard of someone bending a Koxx hub or Koxx cranks. Koxx Cranks
used to have troubles with the steel part on wich pedals are screwed
but this has been solved (as far as I know: I got the new kranks a
month ago but couldn't ride much since the french uni cup... I'll tell
you if the problem ain't solved that way but the new cranks seem to be
bombproof)

Qu-Ax 😉

Ok, maybe not the strongest, but strong enough, and not as pricey as
the other lot.

Which one is stronger? I think you need qualitative testing to determine
that. You can't compare Kris and Yoggi riding on them, as they have
different styles. Furthermore, most everyone else has different styles.
In fact, Kris and Yoggi, probably do not put as much stress on the
unicycles as most everyone else, because they are very good riders and
know the techniques that reduce the stress on themself and on the
unicycles.

The bottom line here seems to be that they are both great hubs, and
until we have actual qualitative numbers, we wont know what is stronger
for the average unicyclist. Other than strength, there are many other
factors in choosing a unicycle, so between these two hubs and the
unicycles that they are available on, I think you need to look at the
other components and choose what's best for your use.

The koxx is stronger.

oh this is a silly question really, they are both superb hubs.

The KH is the more sophisticated design, it has the better hub/flanges
design, hence better overall wheel strength and has a larger Q-factor
on the cranks. (on the side... Koxx cranks do have an offset, just not
as big as the KH.... it is just riding preference here, big Q is more
delicate on control, smaller is smoother.)

The Koxx uses the superb ISIS interface for the cranks. It has a crude
design (but aesthetically nice, IMO), but with a relatively heavy crank
and crude hub. Superb basic strength! very ridged! (Be warned this
puts more load on the to rim and spokes, hence breakages....)

Both are a massive improvement on 2 years ago! They are both way
beyond what the majority of riders on this forum could possibly
assess.

My advice is always buy what is appropriate for your riding style....
thankfully there is not one answer. :-)

I'm pretty sure you mixed up "qualitative" with "quantitative"...In my
understanding:

Qualitative: Crankset X looks strong, breaks once in awhile.
Quantitative: Crankset X fails catastrophically with Y Newtons of total
downward force applied to the pedals.

The "Y Newtons" provides the quantity that makes the observation
"quantitative".

I've only ever used koxx one hub/cranks, i have to sets of them: 125mm
cranks for my trials/street uni and 110mm cranks for my
street/freestyle uni.
They are great, but i wouldent recomend them for muni because they have
no q-factor. I do 1.6 meter drops with no complaints. Koxx one are
definatly better for the price.
