Linears feel terrible IMO, they feel much stiffer than they actually are. It is also much easier to avoid bottoming out on a non-linear switch. I would stick with blue if you don't find the sound annoying, because you will probably miss the click, or if you must switch switches, go to browns.
Also what is the point in Otaku? It is terrible if you don't know the keys 100% (as you stated), there really is no benefit to otaku/ninja, unless you think it looks amazing.
