For me I prefer snaps for afew reasons. I think they look neater & continue to look tidy. They are harder to undo, especially if you place them as side snapping nappies ( yet to venture that way) so less likely to have little ones taking their own nappy off. I find velcro, no matter how its placed rubs Isla's skin, not sure why/how it happens but the few velcro nappies I have had it always happens. Also my sewing machine hates sewing velcro, no matter what I try I just can't make it work.
