Yup, I loved Transformers in the 80s. I will mention another of my favourites that hasn't been touched on yet: Visionaries (the "Knights of the Magical Light"). At the time, it was probably one of the least stereotypical cartoons with refreshing story lines and complex characters (although the bad guys tended to be jokes).
In a way, it was the 80s equivalent of Gargolyes (my 90s pick).
