It's not so much that it's "cleaner". The reason I'd prefer it myself is that it's idiomatic. It's a fairly well-known construct. Even if you don't use it yourself, it's worth knowing because it's something you'll probably see in others' code.

I don't think the same is as true of "${\()}" -- I can't recall ever seeing that before today.
