I was a diehard shimano fan for a long time, but they lost me on drivetrains when 1X arrived, and they fell even further back when AXS was released (which I like, but nobody really needs). I still prefer the feel of shimano brakes over SRAM brakes. Drivetrains in general are so good these days we're talking marginal differences at most. I'd be wiling to try XT or XTR full kit on a future rig, but probably mechanical.
