I feel the need to point out that Machamp is only outclassed by Conkeldurr as a Guts user, since Conk has recovery in Drain Punch, Mach Punch for priority, more power, and greater physical bulk. Machamp still has its own niche with No Guard DPunch's. Also, Machoke hardly has anything over Machamp. It's a little bit bulkier, but that 30 base point drop in attack really hurts, as well as the lower speed. Machoke fails to outspeed Blissey without ample speed investment, and even max attack Adamant Machoke only does 75.91% - 89.36% to 252/252 Blissey, only a 7.69% chance for a OHKO. That's gives Blissey enough time to poison you, set up Wish, whatever. On top of that, if you're running enough EVs for power and speed to beat Blissey, then you're missing out on having the bulk that sets Evo Stone Choke apart.
