From the American Sunbow era, "Dweller In The Depths" is probably one of my favorites just for the fact that the animation quality is probably the closest to TF:TM as you can possibly get in the entire series and feels like an actual sequel to it because it focuses entirely on the movie characters as well.

"Call of the Primitives" has great animation as well...but the style is off. An Primacron is kind of a bad joke to me.

 

You are a horrible person.

 

I will watch The Master Builder any day of the week.

Also, can I put the whole of the first season in second place?

 

I'm more of a season three person (my favorite character is Galvatron and runner up is Kup, so getting to see them is great for me) but if I had to pick one episode it would be The Burden Hardest To Bear. Both Hot Rod/Rodimus Prime and Scourge get focus and there are some nice character moments and interactions in the episode (namely Rodimus Prime and Kup talking to one another about the burden of leadership). Getting to see the usually loyal Scourge betray Galvatron and take over the Decepticons was fun as well. The way Galvatron says "Scourge!" at the end of the episode makes me chuckle whenever I watch that episode. All in all, I would give it an 8.6 (1986  ) out of 10.

 

The pilot was the most memorable episode for me.

 

War Dawn or Ultimate Doom 3-parter

 

Webworld.

 

Call Of The Primitives, end of the discussion.

 

Mostly for Sentimental reasons, but mine would be:
Quest for Survival
Ultimate Doom
Return of Optimus Prime
Ultimate Weapon
Burden Hardest to Bear
Fire on the Mountain

 

I don't know if I could pick a single episode, but I would say Webworld is a strong contender.

 

Whichever one was the one where Hoist and Warpath ended up in the middle ages.

 

More Than Meets The Eye
The Ultimate Doom
Fire in the Sky
Countdown to Extinction
Heavy Metal War
The Golden Lagoon
The God Gambit
Blaster Blues
The Secret of Omega Supreme
The Search for Alpha Trion
The Key to Vector Sigma
Cosmic Rust
Starscream's Brigade
The Revenge of Bruticus
War Dawn
The Ultimate Weapon
Webworld
Starscream's Ghost
Ghost in the Machine
The Burden Hardest to Bear
Dark Awakening
The Return of Optimus Prime

 

Fire in the sky.

 

The Burden Hardest to Bear, sure it was Rodimus doubting himself about being leader for a millionth time but I love how it was handled and how in the end, Rodimus finally understood what it meant to be a leader... Only for the Return of Optimus Prime to come one episode after that and ruined it by completely tossing Rodimus to the side like garbage!

Ah sorry, I just am still unhappy with the timing of the episodes' releases and how all of Rodimus' development pretty much got thrown out in favor of Optimus.

 

In some ways, the series makes a bit more sense overall if you skip season 2 and just go from season 1 straight to TF:TM.

 

Hoist goes to Hollywood is great.

 

Enter the Night bird. They really got their asses handed to them.

 

Ok, fair enough. It is in my top ten.  

 

A Decepticon Raider in King Arthur's Court

 

My favorite is still Blaster Blues. Makes me laugh whenever Optimus tells Blaster to shut up while Jazz spins and dances  

Or the one one when Prime says "A boobytrap that actually catches boobies"
