Tbh it is simply personal choice and intended use. I’m not fully used to my xt’s on my five (2 rides with 180mm discs) but can tell they are nice. Some people say they can be grabby but once you are used to them you can easily feather and modulate the power, However the power does increase rapidly so you need to be used to them.
On the other hand I have the Elixir CR’s on my downhill bike which I race reasonably successfully. Before the CR’s I had codes which like the xt’s had good modulation but ramped up in power too quickly for me and I struggled to control them in sketchy moments and when tying to control speed on off camber high lines, simply because there was too much power and I would loose traction and slide down. I find the Elixir CR’s to have the right rate of modulation and total power for me. I love steep tech tracks and have no issue with power even on 5 minute downhills in the alps where i’m probably off the brakes for 20 seconds of that.
So if they’re knackered then the xt’s are definitely a good choice, but in the end its what type of response you want from you inputs. They just behave differently.
