Wind drift is the biggest one.
.224 Valkyrie, given the stated mv's and known BCs of the 90gr SMK and Berger, will have less wind drift and drop than a Grendel no matter how you slice it.
You would have to get a 123gr bullet with a higher BC than the 123gr Scenar going 2700fps to match the Valkyrie for wind.
That speed is possible with hand loads using CFE223 from 24" barrels, but the only bullets I'm aware of with a better BC are solids like the 121gr Flatline, and I doubt you're going to get much past 2500fps with those, let alone the $62.4/100 cost.
If you made a 107gr or 110gr that is as long as a 130gr Berger VLD in 6.5mm, then you could match the muzzle velocity of the Valkyrie from a Grendel, and match or exceed the BC.
A 90gr with the same BC is going to have less drop either way, but I care more about wind.
