Seriously, I really think Rebel fighters are overpriced. Not hideously so, and not totally useless (put away your bile guns fighter-philes) but just to the point that I never feel like they are a worthwhile investment next to my capitals.
Imperial Aces are very teamwork oriented with the exception of Vader and...well c'mon, he's Darth Vader; He doesn't need any help from regular TIE plebs. Howrunner works well with Swarm based TIEs, Rhymer works extra well with other bombers and advanced, and can even make a cloud of TIE fighters obnoxious at medium range. Fel loves his Advanced bodyguards and wants to be paired with Howlrunner too...they all synergize very nicely. Once again, they're not overpowered (IMO) they just play very well together and really give a sense of a cohesive fighter unit.
Rebel Aces...don't. They're almost like grand-standers with the possible exception of Kayen Farlander who wants someone else to knock a shield down before he dumps some torpedoes in. No can keep up with Tychos ability to disengage, Wedge likes exhausted targets, Dutch likes to MAKE exhausted targets (OKay so Dutch and Wedge work pretty well together) and Luke is more at home in a Bomber wing than with other X-wings. It's like a cloud of individuals instead of a unit, which I realize is sort of the point with Rebel mindsets, but it's makes for....well frankly it makes for uninteresting fighter phases as a rebel.
And maybe it's just me but I have a HUGE problem fielding anything but X-wings because they're just so much better. They're cheaper than B-Wings, gain a speed and an anti-fighter armament, only losing one blue battery armament. They're significantly tougher than A-Wings, and if you're opponent chooses not to trigger the A-Wings counter than they also hit harder than A-Wings, losing out only in Speed. And Y-wings...ugh. I want to like them, I really really do...but I hate them. The only thing going for them is their cheap cost married to a Bomber Black Die. But they're tied down and murdered so easily, even with escorts, that they always feel like a waste of points.
So in the end, I just find as a rebel that fighters aren't worth it. I can field two different designs that bring two Anti-Fighter armament to the table and can even field the point defense reroute on one of them if I'm...focused on fighter elimination to the point of brain damage.
Addendum: I'm looking forward to Wave 2 'cause I think it will bring some spice to the fighter game. Intel means Y-Wings could actually disengage from targets to complete a bombing run, and Rogue means an escorting YT-1300 (or whatev) can give and take without needing commands. Until then though, I feel the fighter game is flat and stale.
