Tabs are like training wheels on a bike. Very useful for beginners, but limiting once you develop beyond a certain point.

Learning notation opens up the whole world of printed music, which is extremely valuable for self-tuition, and makes you a literate musician, on level with other literate musicians. It means you can play from anything, it doesn't have to be specially prepared for you as a guitarist. You can play a piece from notation that you have never heard before. You can't do that from tab - because tab doesn't show duration, and only rarely shows timing.

So I'm with rick-slo here. Any and every learning aid is great. It's possible to learn guitar without tab (every guitarist did, once upon a time). It's also possible without notation. It's possible without either!
But why deny yourself an aid? The point is to understand the advantages and disadvantages of each one, and neither reject nor expect too much of any single one.
