I've never fully cared for the Graflex saber, to be honest, and I partially feel that it's due to the blatant copying of it in other material down the line. It became the "generic" look of the lightsaber for all lightsabers thereafter. But, having said that, I have and prefer the ANH. Not just because of its history but also because of some previous reasons stated above: it's simple, it's iconic, it carries a bubblestrip (which, I think, makes it look more practical), etc.
I think the ESB is just too clunky-looking for my tastes. Aesthetically speaking, its got more recesses and protrusions on it than the ANH which makes it look bulkier and more jumbled looking than it did in the prior film. People draw their own reasons as to why it is in-universe, but from a purely production standpoint of "some bits fell off; we need to fix it on the spot", that's more than enough for me.
It wasn't in the original post but some people went TFA. Personally, I wouldn't want anything from that film.
