If you can't do both, you're crap.
Just jesting!
thats the first time I've seen tab shown in the manner above. Much better than the normal lines and numbers.
If learning a classical piece on a guitar, it's great to know what the key signature is, what position the left hand should be in etc.
I'd go one step further and say that your staves and dots is even better when an indication for which finger is used ie 1-4 for left and pima for right.
More info the better.
I suppose we've all learned differently. Some in lessons and some sat at home with a tape deck, copying each note till something sounds right and the many other ways.
Perhaps one has a better understanding of musical theory, if they can slice up bars visually?
I don't.
