Brownings are a favorite. Oddly enough, I don't own any of their pistols. I've admired Hi Powers many times and thought about it, just don't have much use for the 9mm (except my 3913, that's it). However, the BSS's are great shotguns, their 1892 is better than the original, ditto the 1886, and the B78 (and 1885) is one the coolest, handsomest single shots ever. I need a BL22, even if need really has nothing to do with it.
Oops, almost forgot the most important one! I have my grandfather's old 12 ga Browning Double Automatic with the grey receiver. It was a decent bird gun, choked IC, fastest automatic I'd even shot with it's short recoil system. Kind of a cool shotgun. I take it out in the woods every year. It's not a side-by-side, but still handles, points, and carries pretty well.
BTW, I just got the Feb issue of Handloader and the cover pic is the new B78. Browning (Miroku) started making them again. My old 45-70 and 30-06 are definate favorites. I don't know if the new trigger is as complex as the old one or they adopted the 1885 design. Other than the trigger, actually, I never did see any difference between a B78 and an 1885 except for the Monte Carlo cheekpiece stock on most (not 45-70s) B78s.
