Personally, I like the old Aurora 32nd kit.
Seriously, Acc Min's is the nicest 48th, but I wouldn't build it without the Cutting Edge replacement cowls. That's just me, though...
The 72nd Hasegagme kit is really groovy and blows any of the others in that scale out of the air. It may be the nicest kit in any scale, but I dunno how it fits. I don't build little scale...
As to fixins 'fer 'yer plastic hobby kit,
here's a link to what's currently available from Squadron, which is a pretty good cross section of what's out there; brass and resin. As to which is best, you have to decide what you want to add and which set best suits those needs. But pretty much everything out there is well done with few exceptions. Although this, too, is a matter of personal preference.
Fade to Black...
