XTR is actually different to the XT inside but seems to perform exactly the same tbh. Deore is a big step down imo, not well sealed but just not durable, I destroyed one in 6 hours riding- dents in the races I think. Admittedly in a dh bike but still, XT is up for that.
There’s some good alternatives- Gusset EXT24 is good ime (though the ceramic one was really disappointing). It’s longer lived than Shimano, and is somewhat servicable (removable outer seal) so you can extend that quite a long way. Not as far as Hope but it costs about 2/5ths as much. Also, takes completely standard bearings so easy and cheap to keep going.
