I'll be the first to tell you that personally I think the IDW G1 story has been touch and go. There's been some nice story elements, but only a scattered few a midst a sea of underdeveloped characters and preachy dialog and artwork that is touch and go, depending on personal preferences. Overall this story is really more of the same.
It features the same artwork from Autocracy, as well as most of the other major plot lines from recent years (Chaos Theory, Dark Cybertron). The art has a simplistic retro look with a grimy filter over it. Whether you like it or not will largely depend on if you prefer the original artwork from the eighties for the Transformers. Personally I find it too simplistic and stylized. Also because the artwork is so dark it can be hard to tell what you are looking at sometimes.
In terms of the writing, the story picks up right where Autocracy left off, by lifting material straight from the old animated film. If you are tired of transformers lifting lines and scenarios from that movie (after the live action films, the Prime cartoon, and the Cybertron video games) then this book is going to leave a bad taste in your mouth. Without spoilers the story has it's ups and downs. I like what they do with a lot of the material but Optimus soon devolves into his mopey self, and this time Grimlock is joining him in the moody club. The action is nice, when you can tell what is going on.
It's not a terrible book, but it isn't great.
