theyre pretty much the same except a closed coil has a cover on it which makes it sound thicker and less trebly.

You CAN play anything with anything....but some guitars sound right for some things, and not for others. Single coils sound retarded for metal, though those who are apeshit about harpsichord probably beg to differ.
Closed cover's have a thicker sound and are less trebly, both in good ways, unless you want a shredder, 80s, or any modern metal type sound. Otherwise, I would rather have closed, but in my opinion open looks better. And because the sound difference is minimal, I choose to go with looks over minimal, very minimal, sound quality.
