The answer is probably both.
TAB will help you learn songs more quickly, so you'll enjoy playing more. Reading music is really helpful, and I think of it like a language... how weird would it be to be able to speak a language that you can't read? Or worse still, to copy what someone else says when it could be wrong...
Learning to read music (and music theory in general) was really good for me, and helped me understand loads of other things too... and that helped my playing.
TAB is kind of like 'painting by numbers'.... if you really want to be an artist, you need to be able to figure it out yourself, not just follow directions... That said, when you start out, TAB is the fastest way to start making an acceptable noise with a guitar... ;)
