I have:
Cherry MX Blues,
AJAZZ Blues,
No Name Reds
Most awesome are AJAZZ Blues.
Reds where really hard to get used to, since touching (compared to blues) a switch registers a click, but after a while I got used to and man I like to stream with them.
Blues drain stamina like hell, so I prefer Reds for osu.
If you are getting keyboard solely for osu, get Red switches and get used to them being lite, else get browns.
I would get browns as my first mechanical keyboard
(from choices you gave)
Also both reds and browns will still be loud because of bottoming them down all the way, specially if you come from membrane keyboard (I know I did when I started) so I had to get something like this:
Cherry MX Rubber O-Ring Switch Dampeners (125pcs) to make them more silient.
