CD version vs HD version on Voobly

What are the pros/cons of each one?

I was digging into more details as I feel I've read about it before but didn't manage to find any specific answer (just the steps).

Currently I use CD version + WK (HD-to-TC) + custom hotkeys.

I understand HD version is better for recording/streaming but I'd like to know: are there cons? I feel I read something about custom hotkeys on HD version, not sure.

Thanks
