What is your list?
I have seen several comments in other threads about how ugly some weapons are, to the extent that they are avoided because they are so hard to look at. This isn't really a damage or effectiveness topic, but rather as the title suggests, one about looks.
My list:
Cool:
Hunting Rifle - tricked out to full sniper - pistol grip not so much
.44 Mag Pistol - Dirty Harry - doesn't get much cooler than that.
Deliverer - My name is Bond, James Bond
10mm - Tricked with recon an silencer, so cool.
Mini-Gun - What's not to like
Submachine gun - Gansta, or WWII G.I., fantastic.
Gattling Laser - Don't know why you need gattling on a laser, but hey!
Institute
Laser Musket - New, different....
Awful:
Assault Rifle - looks absolutely ridiculous. WWI Biplane machine gun? Can't stand to look at it. Will never use it.
Plasma Rifle - looks like something a Barista might use, definitely not me.
Gauss Rifle - looks like a real one, but still ugly. FO3 and FONV versions looked cool.
Pipe Guns - C'mon.
Combat Rifle - I don't even know what this is supposed to be.
edit: put in spoiler section so any weapons can be discussed without ruining anything for others...
