For years, I strongly felt there was no reason at all to buy a 5200 as an Atari 8-bit computer owner. After all, the games are mostly the same, with the few 5200 exclusives having been long since ported back to the 8-bits. And the 5200 controllers are wildly known to be troublesome.
My opinion finally changed when I happened to pick up a 5200 for next to nothing at a yard sale. It's just that the 5200 looks and feels like a state-of-the art game system for classic games. The console is so damn big, black, and shiny. The carts are also huge with big, colorful labels. There's just no comparison between a 5200 cart and an 8-bit cart... the 5200 carts are just so much more attractive. Plugging one into the 5200 just feels great. The use of a 2nd button is nice for a handful of games, the Trak-Ball controller is great for another set (Centipede, Missile Command) , and the controller coupler is great for a couple of others (Robotron, Space Dungeon.) A few games were re-programmed and improved greatly for the 5200 from their 8-bit cart versions (Qix, Pac-man, Dig Dug and Centipede.) And it doesn't hurt that 5200 carts are available pretty cheaply on Ebay.
On the con side, well, there's those pesky controllers. Even when rebuilt to function correctly (which pretty much ever 5200 stick needs at this point) many users find the non-centering sticks, mushy fire buttons, and awkward shape less than ideal. Thankfully, there are alternatives, such as the Redemption and Masterplay adapters, the Wico analog joystick and (my personal favorite) the 8-way Coin Controls Competition Pro joystick. While none of these are common, they certainly can be found with a bit of effort - with the Wico and CCCP being easier to find than the Redemption and Masterplay adapters.
As an Atari 8-bit computer user for over 25 years, I've been shocked at how much I enjoy the 5200. Yes, the games are largely the same, and yes the standard controllers are substandard. But it's got a certain special charm to it that I would recommend experiencing... at least "just for giggles." :-)
