22" for me. I shoot suppressed so I don't want to have too much extra length to deal with. This is a new barrel so I don't have any chrono data yet, but my 22" 22-250 AI shoots the 88 ELDMs at 3150 w/ RL-23. I'd expect my 22 Creed to do the same or better.
I've owned 22, 24, and 26. I like 22in for woods hunting. 24 in is a compromise of both. If you hunting open areas I'd run a 26. More velocity with a 26
22 and 24. Personal preference. If it was for LR hunting varmint I would run the longer. For shorter distances and for packing thru brush 22. Without plans for suppressor I would likely go 24".
