Since this was posted in the Shotgun Forum... I'm only going to comment on shotguns.
The best: Remingtons & Benellis
The worse: Tristar
In other quarters I've heard many complaints about Tristars. I wouldn't recommend this shotgun to anyone. Period.
I own 2 Remington 870's haven't had a bit of problem from either one. Both 870's are over twenty yrs old. One I use for home defense & the other I use for turkey hunting, competition, etc. Remmy 870's are the most sold shotgun, there's a reason why.
Benelli shot guns are great performing shotguns. I've shot friends' many of times & hope to own one soon. Last time at the local gun store they had a Benelli Nova w/ camo stock marked down to $409. I wish I could of afforded it.
One day soon...
