It comes to this. Tab is good to show you where to put your fingers. But standard notation tells you pitch, rhythm, harmony, and context. As we play a stringed instrument there are multiple places to play a specific and tab deals with that nicely, assuming the tab is actually a good way to physically play the part for you. But it conveys no information regarding how this note relates to any other notes, nor does it allow you to see how your part fits with the other parts.
I liken it to the difference between reading a schematic (a REAL schematic) and looking at a wiring diagram. The diagram will give you a way to hook up wires, but it doesn't show how the circuit works. The schematic tells you what's happening. And I feel that knowing what's happening is very important. The only "bad" thing about tab (assuming it's accurate, but the accuracy of most tabs has nothing to do with its efficacy as a learning tool) is that it perpetuates the fallacy that playing an instrument is about putting your fingers in the right place rather than being about making music. The old Bach joke notwithstanding, music is what's important, not the instrument.
