Otterbox needs no introduction at this point. They've been around for years and always make extremely durable cases.
Here's the thing, Otterbox cases are nowhere near being "slim". If you're looking for an extremely rugged and durable case that can handle almost anything, this is what you want. If you want a somewhat thin case, don't even consider Otterbox.
People who use Otterbox know what they have to offer. If your last case didn't keep your phone safe, this might be the next step. This is one extremely rugged case.
