Does the Zwift community think its necessary to own a high-end power meter in order to see significant improvements in performance and overall experience, or is the lower-end option sufficient for those just starting out with structured workouts and training plans, taking into account the Zwift Companion App allows for the use of all sorts of external power meters, including those not specifically branded for Zwift. In other words, do the benefits of a high-end power meter justify the substantial cost difference, considering the lower-end option still provides accurate data and seamless integration with the Zwift platform, or are the added features and accuracy of the high-end power meter worth the investment for serious cyclists, and if so, what are the key differences that set them apart from their lower-end counterparts. Does the Zwift community have any personal preferences or recommendations for power meters that work seamlessly with the platform, regardless of budget, and what are the pros and cons of each option, specifically in regards to their use with Zwift, and how do the different types of power meters available, i.e. left-side only, single-leg, and dual-leg, affect the overall Zwift experience, if at all.
