I didn't like the Grip fb knife - just felt weird to me. I like the BM 201 Activator+ (D2), so I ordered one. It's a great fit to my hand. The Alpha fb doesn't feel - or look - as good, to me, as the Kalinga Pro in S30V. That was a great buy here. So, now I will compare the Activator+(D2) to the K-P (S30V).
I bought the Activator+ as my second Benchmade. Like my first - a Grip folder 551 in 440C - it came dull... very dull. Bucks come sharp - and the 408 fb K-P (S30V) came razor sharp - and still, admittedly after little use in the last 1.5yr+ that I've had it, is push paper-cutting sharp. As to price - the Activator+ may be ~$20 less than the K-P with judicious evil-bay shopping. ($80 & $100). That D2 is a chore to re-edge - even with a clean Spydie Sharpmaker. Buck & Spyderco Native S30V seem more straightforward - and maybe a tad easier to re-sharpen.
My use is camping - wood's chores - bushcrafting - and some 'food prep'. Probably my favorite Buck for such is a 192 Vanguard - available in a mix of upgrade blade material, like S30V & 154CM, as well as utilitarian 420HC. I still like the Activator+, but it had the misfortune of arriving here with my first Bark River - a Huntsman, which now has six siblings, all carbon steel and convex ground, not to mention my best choices for bushcraft use. Still - I can't quite break the ties with that BM Activator+ - it is a keeper, even without an exact purpose here. Here it is with the Vanguard and Huntsman:
Here are the Folding Kalinga Pro (#419), Fixed Kalinga Pro (#408), and a 110 for scale comparison:
