Welcome back. I'd choose a kit, but before buying it, ask the helpful members here for any opinions on how easy it will be to build. We can give you feedback and tips on any kit you chose.
Remember that many of the AMT or MPC kits you grew up with are out there in fresh Round2 boxes at HobbyLobby or the LHS. They have nifty pad-printed white walls & great new decals, but it is the same well loved plastic in the box. And Round2 kits now feature a parts layout drawing on the bottom of the box, showing everything you get in the kit.
Good Luck! and Happy Modeling!
