It's actually consistently well-written by Jeff Parker, and has some great art by Gabriel Hardman. I really enjoyed it. The books shouldn't be too expensive to pick up, and there are several trade paperbacks available for you as well.
The What If issue was one of the first non-distributed, American import comics that I ever bought, here in the UK, back in the 70s. Besides that, like you I've always been quite fond of this retro team, and Agents of Atlas gives some 50s background stories as well as being a modern update. I suspect there's a very good chance you'll enjoy it too.
