I’ve had 575 and done a few demo’s on both the Trek Fuel and Remedy. (Just for reference I moved from the Yeti to an Orange Five and have to say I’m much happier on the Orange. Always felt the yeti was a little twitchy)
Judging by the Antur comment you like your downs and while I enjoyed the Yeti downhill I wanted something a little more stable down and stiffer for climbing.
Simple comparison the yeti is a bit more lively than the Trek but the trek gave me a bit more confidence and climbs better in my opinion. Depends how you like your bike. Also the shock on the Trek just progresses through it’s travel in a smoother manner, the second chamber gives you a cushion on iffy landings.
They Yeti was a lovely bike though I really enjoyed mine over the year I had it, so please don’t be put off by my opinion.
I’m thinking about trying something new this year and looking at getting a Remedy or the Lapierre Spicy. Other things to look at are the Moji Ibis and the Santa Cruz Nomad. Not a definitive list but things to consider, then get drawn in many other directions from there.
Hope that helps.
