I rank US season two over season one. Those were the episodes I saw most as a kid and have the most fondness for. Possibly helps that season two has a lot more episodes. It definitely helps that the cast in season two is a mix of the whole 1985 toy range (still my favourite range of characters ever).
I'd also score Season two higher for it's great multiple part episodes. Season one's Ultimate Doom is not very good, but season two gives us "Dinobot Island", "Megatron's Master Plan", "Desertion of the Dinobots", and "Key to Vector Sigma" - all great two parters, as well as the unofficial two parter Combaticon episodes.
Masterforce is terrific, but if I could have only one series, Season 2 would beat it out so I've placed it second.
