For me it was Beast Wars and Beast Machines they are to this day my all time favorites. David Kaye is the best actor to ever play Megatron. I mean seriously there was something about his portrayal that was so unique and I loved Megatron's clear arrogance and narcissism it made him seem so much more evil than the other versions.
It's ironic that I never knew the actual titles because in TR: Robots in Disguise. I saw autobots and I'm like "Wait what?" Then I see Predicons and I'm like "Oh okay." Then I see the Decepticons and I'm like "Wow Awesome!"
It wasn't until the Unicron Trilogy I realized the true plot form of the series. (I was a kid cut me some slack.)
