Magnetic is less expensive, but fluid gives a more realistic road feel. With magnetic, resistance is constant, regardless of speed, so the better magnetic units have a switch for multiple resistance levels. With fluid, resistance increases with increased speed; thus, you use the gears on the bike to change the resistance. IMHO, this advantage outweighs the difference in cost between the two.
I have both kurtkinetic.comroadmachine.phpOpen ↗ and cycleops.comfluidsquared.htmOpen ↗. I use the Kinetic, and my wife uses the Cycleops. Both are very good. The Cycleops is more prone to problems (oil leaking out of the chamber) than the Kinetic. It has never happened to my wife's unit, and she has been riding it for an hour per day, five days per week for two years. If the unit fails, the coupany is very good about replacing the entire resistance unit under warranty.
It is more difficult to put the bike on and off the Kinetic than it is the Cycleops, but the difference is minor.
