I know the advanced is 5 points more, but it is an effective delivery system and can fight as well.

They are sturdy like an Advanced and they have target lock - which gives them a better chance to hit - just like an Advanced. Ok, Tie Bombers have difficulties in turning in tight circles ... but they are pretty good in zooming out and engange.
If you like your Advanced use it right away, of course. But i have a different list for you, which actually was quite effective:
