>>7145380281 is great if you wanna play diet red orchestra on 200% dmg servers, otherwise it can be very very bad
4 is good if you want a modern setting and like advanced movement, you can b-hop and airstrafe to your hearts content but its balanced out by guns having little accuracy while moving. it's my favorite but a lot of the maps are terrible for CQ. I play Rush and its a lot of fun it makes the game 10x better. CQ is still fun but it greatly depends on the map and whether or not you like PTFO-ing
