What is your best class in modern warfare 2

So far I called 8 Nukes and 4 of them were this class:

Tar21-Silenced
M93 Raffica-Silenced
Equipment-Claymore
Special Grenade-Stun
Perk 1-Scavenger Pro
Perk 2-Stopping Power Pro
Perk 3-Ninja Pro
Deathstreak-Final Stand

I hoped you guys liked it and I would be glad if you call a Nuke with this class.
