To be fair, I can find plenty of mirrors with decent, if not superior subs. Not saying that there's a lot of good mirrors (especially for older shows) but streaming has its merits.

I'm sure we have several threads around here about streaming sites, but for quick reference I typically use
animedreaming.tv
kissanime.com
animeseason.com
m.realitylapse.com (iTouch)
m.animeshippuden.com (iTouch)


Sure there are plenty of better streaming sites, but I've been fine with these. The first three are free, no sign-up. The last two are the same, for mobile at least. Not sure what they're like on desktop
