There's also a combination of both, as @griffpatch does in his tile platformer engine, so you can totally put slopes in tiles. Personally I'd tend to opt for tiles because they're much easier to work with and make levels out of.

My rpg engine is top down, as most are which don't allow for slopes because you can't have slopes top down lol, but it allows for more precise collision detection like griffpatches engine uses pins, mine uses something different and faster.
