Hermes I have a Tacx Neo 2T (also have an OG Neo I use for my TT bike) and like them a lot. I like the Neo because it just works and responds quickly. The new Kickr doesn't require constant spin down calibration anymore, so it just works now too apparently.
TMonk I used the Zwift FTP test workout for mine. It flips to resistance mode for the test, so you get to control the power but aren't at the mercy of the road. I always pick a route like Alpe du Zwift so it feels like I'm climbing when I do it and I get the best of both worlds.
