I’ve only done Ae, Kirroughtree, GlenT and inners but that’s my order of (increasing) preference.
Ae is flow and up and down all the time and you never feel like you get a good decent until the very last bit of Omega man.
Kirroughtree was more technical features on the climb, granite slabs interesting but the black is a load of climbing, so strenuous rather than tough features on the down.
GlenT natural stuff is amazing and Spooky is always fun, as is Cool Running. A lot of the red is cutting up.
Inners is a big up and then down. Caddon bank is fantastic. Never tried much natural there but tons if you’re looking off piste.
