Is Caterpie Good in Ruby & Sapphire Playthrough?

Not native to Hoenn. Trade from FireRed or LeafGreen. Butterfree gains AbilityCompound Eyes in Gen 3, which boosts MoveSleep Powder accuracy to 97.5%. That's the one reason to consider importing it. Everything else about Butterfree is still underwhelming.
