Mercenaries vs. Raid Mode?

Is there any real difference between these modes? Is either one better or worse? I know that Raid mode has coop, but other than that, are there any other big differences?

Raid mode is supreme. It is almost like a RE RPG built within the game. You do specific missions (not just survive until the clock runs out), and you can level up your guns/characters to get sweeter stuff. Its WAY better.garrett_duffman

Mercenaries is more time based arena mode while Raid is going through levels from SP with more enemies and ammo and leveling up and getting weapons and parts. Personally I find Raid Mode much better then Mercenaries. It more customizable and has more content overall. If you into scores through you will be kinda disappointed as they don't save what you got after beating a stage.

Raid Mode by far. It's just an absolute blast, miles ahead of the time based Mercenaries I just wish there was better communication between players. Someone I was playing with kept making their character say "over here" or "c'mon" or something.. Does anyone else know how he was doing that?JoeInWonderland

I think it was either up or down D-pad but I haven't tried it yet.
