Have you ridden both? Your trail conditions are very different to mine, but FWIW I went Trance X.
I demoed the Anthem X as I was looking for a 29er option to replicate my raceable XC 26er, however I hated the handling and while the rear suspension was very capable it felt a touch too firm.
I then demoed the Trance X just because I was curious to try a trail bike. The handling felt almost like my 26er and the Maestro system controls that amount of travel pretty much unnoticed on the climbs, and the longer legs are a blast. It changed my thinking to having a trail bike and my existing XC bike, rather than 2 XC bikes. This extends my riding opportunities especially as I’m getting older and quite a bit slower now.
