Most likely, the drop version is more performant.

Honestly though, in most situations you probably won't notice much perf difference between the two. It's most likely just Java arraylists underneath at runtime anyway. By what you're doing earlier you're merely adding another layer of indirection that could probably be JIT'ed away. Then again I could totally be off on this so maybe someone more informed can correct me.
