I could see diceless being good if you're really solid about the scope of your RP, but just about anything I do ends up needing a map and various supplemental materials anyway. Out of the games Fallout New Vegas is pretty nice since you can lift IRL maps as source materials.
Post-apoc stuff tends to get equipment oriented very very fast in my experience. Like I recently purchased the Roadside Picnic Tabletop sourcebook, and it's got this weird combination of a lot of rules to remember for purchasing equipment (down to how much money you spend in character creation), defining abilities, weaknesses, but nothing really for dice rolling / conflict resolution. It would work okay in person I think, since it's really more of a puzzle / critical thinking game ("How do I get through this death-anomaly given my character?") but it did point out challenges that post-apoc / survival kinda plays present.
I think Fallout in particular lends to more stat-tracking and a definite inventory, so most people go for D20, GURPS or something in that vein. You'd probably have huge character sheets. And trying to get granular mechanics for ghoulification, super mutant mutation... yeaaah.
I actually think Fate would be really good for it (but obvs biased given my background) because FO is a combination of sorta-realistic post-post apoc and really pulpy supermutants and energy weapons. The Aspect system lends to keeping equipment tracking from spiraling hopelessly out of control, too, and stunts play to the unique brand of crazy it offers. I'd probably reboot my FONV campaign in Fate if I had time and energy for it.
I m unfortunately a bit thin on what systems I have used though I want to avoid d20 systems for Fallout because I want to retain that Fallout feel so would prefer a d100 system. My first thought is 40k RPG as a base since it has that initial lethality until you get power armor, is gear based, uses skills and perks, uses a d100, and I think I could get the right feel for Fallout from it.
