I prefer tab, but I'm wanting to change over to notation. Actually getting the stuff without buying books is hard though (and books usually include tablature, which I always end up glancing at).
While notation does have extra details on it, it doesn't tell you where to play notes, which can be tricky at times, though I guess that comes with practise. Also, harmonics are weird with notation, I need to work out how to find their note value. Either that, or Victor Wooten wrote his stuff out wrong.
