Yeah, ASIO helps make the delay/lag go away, it's much more real and fluid.
If I move a slider I here it pretty much 'now'.

Makes a lot of aspects to music creation better (if you have ASIO available).
If you don't, you could try ASIO4All .. it's a wrapper (not true ASIO) but usually better than nothing.



Make your sound your own!
.. I do not work here, but the benefits are still awesome
