I have Kick'r core which I have had since October, I love it. I have a fan that goes with it that can vary based on heart rate or speed, and use apple TV as my set up. I use zwift, a little, but find Rouvy and Ful-Gaz much more realistic. Rouvy is based on videos taken from a car, sort of like Google Street view, and Ful-Gaz is based on videos taken from a bicycle. Both have advantages and disadvantages, and both come with a free trial period, I think two weeks, so you can try them out. One thing to look at is your wifi speed, if you don't have a good router, you won't get optimum performance from video based platforms.
