Odyssey 2 are the best carts on the list, and I played the hell outta it as a kid so I have that nostalgia. Famicom carts do look great from above in a drawer, with all the fun colors.
I like how 2600 carts are awesome, 5200 are so so, and then 7800 are complete shit. Kinda appropriately follows the life of Atari as a business.
NES carts are fun, I was also always a fan of the special SNES carts (Killer Instinct, Doom, etc.), but N64 carts are awful.
