I agree that standard notation is better. But tab can be useful if you want to write down something fast just for memorization.
As a kid, I learned music in the conservatorio. So standard notation is the norm for me, it's just like reading texts.
It's only recently, that I looked at tabs because they're so easiest to find on internet than the scores sheets!
I can assure you, for me it's way faster to write something I want to remember in notation than in tabs!
That said, if there is no expectation of anyone else ever having to read or play from what is written and you can record sufficient information to serve your own purposes in the future, then it really doesn't matter how you write stuff out...
That one is interesting too!
I used to play in a band with a fantastic singer, which in spite of his great singing, could not read music notation. He had is lyrics written on a folder, and started making annotations concerning beginnings, ends, choruses, breaks, bridges and so on. After a few years, he had developed a personal notation he was the only one to understand. It costed him tons of energy of brainstorming and imagination to re-invent (in a poor way) something that was already invented 500 years ago and polished by millions of musicians since: the music notation!!! I mean if he had spent as much time and efforts to learn to read & write music, he would have had all the information he needed to sing his songs, AND all other songs ever composed!
So, IMHO, music notation is one of the tools a musician uses to do his job. Like a wrench is for a plumber. If you don't have the tool you can always find an alternate way to do the job, it just will be longest, hardest and there's a risk it will not be as well done.
So come on, learn it! Don't be afraid, it's the start that's difficult, after that, it's all bonus!
