I don't think one is preferred over the other in general.
Personally I prefer into, I find it generally more useful in more
situations.
If you are merging sets, or any seqs for that matter, `into` is useful.
(into #{1 2} (for x...))
I'm not sure about speed. `set` calls a PersistentSet Java factory method
and `into` uses reduce. I would imagine they are pretty close. NB:
speculation.
Thanks,
