I feel as if tactile feedback might be necessary to differentiate the clicks while streaming/jumping,etc.
Although, a lot of high ranked osu players go with reds
I, myself, suck horribly; I use 62g ergo-clears
If your friend just wants a board for osu and doesn't wanna deal with customization, just get him a retail mx red board

Edit: Another thing to note is whether or not your friend uses z/x alternately or just one button for his click. Might just be me worrying if it'll be too hard to spam one key on a blue/clear, etc.
