I think, I couldn't care less, except for keeping a straight end cable for recessed jacks (strat or ibanez-style), my right angle plug of choice fits them as well (as well as a tele jack), but I don't like it visually.
most of my instruments have a side-mounted jack, but only because most instruments come that way. I don't really have a preference, any type is good for me.
