I think most emu cores can handle OoT correctly, so you wouldn't have a problem picking an emu. 1964, PJ64, Nemu, UltraHLE 2064, an others are good choices (i posted them in no particular order).
I think you'll to take a closer to look plugins, video specially, since the graphical performance/quality would depend on both the plugin and video card you use. Surely some others user will tell you in details what's best for what.
