The fun thing with the guns is asking yourself "Do I want something fairly fitting to the lore, or do I want 6,000RPMs of 'Fuck You' to send across Tamriel?"
I personally went the more lore-gentle path, but only because I couldn't find a pack that added voice lines from Blood In The Sand. If I could have gunned down Nazeem while unleashing a "BITCH TOOK MY SKULL!", choice woulda been made.
