Vehicles: Some people like Battlefield for the vehicles, that's true. BUT there are also people who like Call of Duty because there aren't any vehicles.

Realism: Battlefield also has its faults. Reviving people with defibrillators isn't realistic. The splash damage of RPG's are virtually non-existent. You can blow up walls with medic/ammo packs. You can just stand next to medic and ammo packs to get healed. Sniper rifle scopes always glint to give away your position, even in night maps. Antennas are sturdy enough to stop a jet and make it explode. You can spawn on squad mates. You fix vehicles by just burning it with a welding torch. You plant and defuse bombs just by standing next to an M-COM. EOD Bots and MAVs can run over you. Instead of picking up the weapon, you pick up the ENTIRE KIT of the guy. Going out of the map makes you die. Et cetera.

Death Menu: Call of Duty also has classes. It's called Create-a-Class, and you can customize them all you want. There's lesser freedom in that in Battlefield.

Squads: You mention realism then mention squad spawning. Squad spawning isn't real. Then again, spawning in general isn't real either. Call of Duty is slightly more realistic than Battlefield in terms of spawning then.

And with Call of Duty only introducing vehicles NOW. That is a lie. You whipper-snappers keep forgetting that there were tanks and jeeps as far back as Call of Duty: United Offensive.
