I wonder if my opinion about these wave 4 ships is effected by where I saw them first.
For example my first experience with the E-wing was in the comic Dark Empire. I loved reading the comic. It was a ton of fun, but it took the Star Wars story line to weird places. I never really had a problem with the story until some one told me there was such a thing as Star Wars Cannon. That the Luke Skywalker from the Timothy Zawn, Heir to the Empire series was the same Luke as the Luke from Dark Empire. That ruined it for me. When Dark Empire was a cool story about, What if "the Emperor isn't dead, and he has like a billion clones of himself, and one more thing you have to turn evil, it is a requirement to beat the Emperor." to no all that weird stuff that actually happened. (Honestly the idea that anything "actually happened" in a fictional universe is a little too much for me). But needless to say there were lot's of things about Dark Empire that I didn't love. And well, saying that it is cannon, and having E-wing's show up in latter X-wing books, because, well, they had them at the battle of Mon Cal, was lame.
Is that why I hate the E-wing, who knows?
The TIE Defender on the other hand par the ultimate ship you could get in the TIE Fighter PC game. I loved, loved loved that game. I never had any problem with it being added (or not added) to some sort of Star Wars Cannon. So maybe I like the TIE Defender more for that reason.
The first time I saw the Z-95 it was in some concept art for Star Wars. The sketch that is clearly an Z-95 was an early design for what became the X-wing. Not an early design in the Star Wars Universe, but in our (the real) world. The first time I saw the Z-95 referenced in universe was in the original West End Games Star Wars Role playing game. I loved that role playing game, but I still think of the Z-95 as the X-wing before they made it look not-ugly.
I have never really heard of the TIE Phantom. I have seen pictures of it here or there, but never really knew anything about it. I am pretty ambivalent to this new ship, may this is why.
