I voted for the second one. As far as tab goes, I sorta go with Jeff Berlin, but that's not part of the pole.
Being familiar with standard notation is a good thing because it's a communication tool with so many different sorts of instruments and musicians, so if a person's going to take the time to learn a language, it's most practical to learn one that most people speak, so to speak.
But by 'learning' it or being familiar with it doesn't mean one has to be able to rip through a Bach violin piece perfectly the first time through. There are guys that can do that, but in my opinion even the guys in orchestras can't do that. That's why it's written, so you can go back to it and refine it and work on certain part over and over again. I think most orchestral guys have to do that to a certain extent.
That said, I think it's FAR more important for a guitarists (in particular) to develop their ear, but have standard notation available in the background; like a small program running in the background on the computer; it's there running, available, loaded, but not always called on.
Tab, in my opinion works in direct contrast to relying and developing the ear because it's basically what some other guitarist heard and you're now relying on their ability to hear rather than your own to a certain extent imho.
But that's a whole 'nother story
