>>22356421Depends on what you're asking about. Do you mean design or competitive usefulness? I think he's a pretty decent looking mon. Competitive wise though, he sucks unless you run him mega or do some kind of trickroom team to support him, or better yet both.
I ran an interesting set with him back in the early xy OU. It was something like: Aggron@Aggronite
Careful 252 hp 252 sdef 4 atk
Stealth Rock
Iron Head
Earthquake
Super Power/Dragon Tail
He makes for an alright lead/support. You could also go for something a bit more aggressive with Attack evs and Automatize to set up some speed boosts and wreak havoc.
