Perhaps you should add the G&G AKsto the list. (or VFC, but they're too expensive I suppose).
Anyways, between those 3, Id take the ICS. All the newer ones are preupgraded internally with a bunch of things (google it). Plus, the CA and TM have unrealistic bolt assemblies that cannot be moved back anywhere near as much as a real gun. The ICS one also can be stripped more realistically.
I've owned the ICS, it was solid as hell. Get it, you won't regret it. Yes, that rhymes.
