I inherited most of my cleaning supply preferences from my dad:
Gun Slick grease (Lubriplate or RIG as alternatives)
Outers Super Nitro Solvent
Outers, 3 in 1, Wahl or sewing machine oil--in no particular order.
I have been playing with Eezeox and Kroil, but not for normal gun cleaning chores (Eezeox for treating surface rust on an vintage 870 Wingmaster I happened upon, and Kroil as a "release" on bullet molds)
I'm finding chain saw bar oil and dry bicycle chain lube rather intriguing. Of course, it has to be extra virgin olive oil for the Beretta!
