This was kinda tough, but
I had to go with "Girls..." The video alone is one of the best around, an absolute classic. Motley Crue was great too, especially around that time. Obviously they had the better albums overall throughout their career despite not putting anything out for awhile.
Guns hasn't put out anything that good in a much longer period of time though. Don't even talk about "The Spaghetti Incident?" because that was just terrible!
Sure, they could've carried on after
"The Spaghetti Incident?" & made something great to heal the wounds, but they didn't. Period! In other words, they haven't made anything worthwhile in around 20 years so it's a major disappointment for fans, especially/including myself.
Motley Crue has/had atleast 5 good, classic albums while Guns only had 2. Motley Crue's
"Girls..." clearly wins this not so much because the song's better (they're both equally as good), but because the band's been better, consistently putting out better albums throughout their career while standing the test of time. They just gotta be the winner any way you look at it.

By the way,
I think that "Mr. Brownstone" should've been up there in place of "Paradise City" for many reasons. I believe that
"Mr. Brownstone" is the better Hard Rock song that would be great played live. They're both good Hard Rock songs, but
"Paradise City" doesn't do it as much for me despite the fact that I love the song. Oh well. To each his own.
