Claw, but not by far.
I actually used an Armaldo on my E4 team in my first playthrough of Sapphire - it's still one of my favorite physical sweepers, even though it's a bit too slow. Great design, great stats and great movepool.
Cradily is pretty awesome too though, and in an entirely different way. It's a great staller/annoyer and actually hits reasonably hard for as primarily defensive as it is. And personally, I love its design.
