While Furman's IDWverse is good, his work on G1/G2 Marvel was better... especially considering that he was a bit more restricted then because he was under the dictate of Hasbro whereas under IDW he seems to have more freedom. I like the story of how Furman wrote a completely ridiculous script as a joke to see if Hasbro was even paying attention to all the stories that they'd been approving -- they disapproved it.
Nostalgia's also a big thing having grown up reading those comics -- I share damnyouhussies' sentiment; to me G1 fiction was the comics over the campy cartoon.
