I does have impressive performance for a 7mm bullet but I would personally question if the advantage translates to real life.
At 300 yards, it appears to have about a 3" trajectory advantage over a same weight 7mm-08 and about 400 extra ft/lbs.
To my thinking, the extra energy is "nice" in theory but unnecessary in real life, translating, in the real world, to a disadvantage in terms of recoil while the extra energy is lost in a tree on the other side of the critter.
3 inches of trajectory at 300 yards is an easy compensation, insignificant to me. Maybe, if I were guessing range, I'd take all I could get but I wouldn't even consider a shot at long range without a laser measured distance, so it's no advantage to me.
Short answer, I don't like recoil, I will rarely, if ever, get a shot at beyond 350-ish yards and I don't kill things that require more energy than the 7-08 can provide, so I would go 7mm-08 rather than .280AI. If your considerations are different, your choice might be too.
