Both great. Get them both.
CO2 is my favourite game ever. Nothing compares to it in terms of what the dev is trying to do with the AI, imho. Command level is scaleable, but usually, I've found, you will need to command at Bn level to make it work well. Even so, it's amazing what the AI does for you, and amazing how the enemy AI can often come up with really solid plans and reactions. Some people, however, don't go for this and want to have a more hands-on experience, which you can also do with CO2, micromanaging as much as you like. CO2 seems much less like a board game, to me, more like the kind of experience CMANO aims for too - real time command. The maps are astoundingly good, in my opinion - no hexes, superb historical accuracy and detail. And CO2 is historical, of course. If you have to choose between then this might be a clincher, as Flashpoint is all hypothetical at the moment, so if you go for that then CO2 will not be for you.
But Flashpoint has a really nice rythm to the gaming experience, caused by the we-go mechanics, and you can easily have a real blast with H2H with Flashpoint. The only H2H with CO2 is real-time and that can be hard to set aside time for. I think there's a larger programming team working on Flashpoint, so development progress through the hiccups might be quicker, and this can get to be important, as I'm sure you know. There are always bugs - in both games - both games are always in continuous development.
But, as I said - get them both!
