Transformers have a rich history in comics but have been subject to numerous reboots over the years because of publishing decisions, bankruptcy, etc. IDW has the license in America right now, and several series that were mixed bags had two excellent books running at the moment. I really don't know if someone could jump in and enjoy them, but one of them had me paying for a single issue of a comic book for the first time in maybe ten years.
At this point the war with the Decepticons has ended with the rebirth of Cybertron. The planet is unfortunately very hostile after the changes it has been through. The Autobots and Decepticons are faced with the challenge of integration. Having "won" the Autobots have to stumble through tough decisions on how to use their newfound authority and exactly how much force is acceptable to keep their old enemies in line. On top of that, there is a sudden emigration of neutral bots that stood aside during the million-years-long war that decide to return home now that the smoke is clear, and they have a totally different philosophy about who should be in power and why. They view the Autobots as tyrants and warlike.
Transformers: More Than Meets the Eye deals with some robots that have gone off on a Quixotic quest now that hostilities have ended. It is oddball, funny, interesting, and tense and the creators have said they take inspiration from Justice League International, the classic funny years of the DC comic. Transformers: Robots in Disguise deals with the political situation and stresses on the rebuilt Cybertron. I'd recommend either, but the former is probably a better book to read if lacking frame of reference.
