LO Hitmonlee is a beast, I find there's rarely a moment all that speed is needed other than for other scarfers.
I've used them all, but then again I've used corsola and octillery :P
But yeah, sites like this are full of people looking for anything and everything, you're bound to find someone after them all. If all else fails you can shove them in the GTS, but none of the pokes up there are "WTF wUd I wont dat 4!!!1111!!!" lol. All are vary viable pokes that can be used.
