My 2 cents:
(A) Bullet placement counts for a lot. Slip a 130/140 grainer in either the Central Computer or the Engine Room of what you're shoot'n, and it will hit the deck.

(B) If you could (Hypothetically) hand a deer a questionnaire after it had been hit by a well placed shot with either projectile (construction and speed being more or less equal)and ask it to fill it out, the answer would likely be:
I dunno mate, I'm dying, youre splitting hairs worrying about 10 grains

Good to see you back, @Max Headroom!

I think most deer would want to be shot with the round that gives the highest chance of a quick, ethical kill. As most have said, that means the most accurate in your rifle, so try both.

If they're both similar, then I'd go with the Superformance. The higher BC and extra weight will give that bit more room for error especially at longer ranges or in the wind.

The SST projectiles in the Superformance ammo get a bit of bad press for blowing up, but in my experience they work okay if heavy-for-calibre and the 140 grainers were fine in my .270. If you were doing mostly close-quarters stuff then the Whitetail might be a better choice but it's probably splitting hairs.

Cost should only be an issue if cheaper ammo means you will practice more.
