Do you find it easier to get kills in Black Ops or in MW2?

It's much easier to get kills in Modern Warfare 2. The damage is much higher, stopping power was in the game, and the guns had only bullet spread and no recoil. You could also carry much deadlier and accurate weapons, and the killstreaks stacked up so that you could get your first 5 kills and then another 3-15 for just sitting back and using air support.
