For the most part, I've really liked what IDW has done with the property. I really liked Simon Furman's initial minis, even if his run did end on a whimper. He mixed enough new elements into the Gen 1 formula to make the IDW-verse its own entity, rather than just a retread (see Dreamwave). All Hail Megatron was fun in an action movie sort of way, but the story was pretty shallow. The Earth-based follow-up was too movie-like for my tastes, and was generally just boring.
The two current ongoings are great. Robots in Disguise doesn't always have a ton of action, but I've really enjoyed seeing how both factions are dealing with the end of the war. Starscream, in particular, has really shined in Robots in Disguise, and, unfortunately for the Autobots, he really is the type of leader Cybertron needs right now. I have liked More than Meets the Eye both for its world-building elements (seeing how the rest of the universe regards Cybertronians has been insightful) and its emphasis on character (as both Tailgate and Hoist state, almost everyone is suffering from some sort of serious personality disorder due to the war). Again, we don't always see much action, but my favorite parts of the story are generally the character moments rather than the action sequences.

I'm more of a classic cartoon fan, so the whole thing being built on the movie combined with some Dreamwave and Marvel UK stuff doesn't always work for me. But still, they are good stuff. Except with certain artists do an issue. That's a fail for me too, but most of the time, nice to look at even if the characters are drawn differently from time to time.
IF you are a fan of the classic, you may not like the fates of some characters at all.
The IDW comics really don't incorporate much from the Bay movies, except for the fact that Cybertron was rendered uninhabitable by the war (emphasis on "was"). The designs and personalities are straight out of Gen 1, albeit more the Marvel comics than the cartoon. The number of deaths are characteristic of the Marvel comic as well, although there have not been nearly as many MAJOR deaths so far (two big deaths were subsequently reversed, and given where RID is heading, a few more may be as well). The first ongoing took some story elements from the movie, but thankfully we're past that now.
