Classics series/Universe Classics hands down.
You're kidding, right? Everyone knows that the answer to this is Transformers: Armada.
Mini-cons.
Incredibly well thought-out gimmicks.
A selection of the greatest TF toys of all time.
Red Alert
Megatron
Hot Shot
Scavenger
Thrust
Tidal Wave
Overload.
Jetfire
Optimus Prime...
God the list just goes on and on and on.
Armada is basically the pinnacle of TFs since the turn of the century. I can't imagine anything equalling it.
--Boltax.
(For the record my favourites from before then are, in chronological order: Gen1, Gen2 and Beast Wars)
For me, Id have to say G1 - the original and the best.
Classics/Universe is a close second, followed by Animated, Animated, Alternators/Masterpiece then the Movie-verse.
I know what many people are thinking, the TF movie line does have QC and design flaw issues, but there are some gems - the Leader Primes and TF1 '08 Camaro Bumblebee. Paint apps are problems throughout all the lines so it's the character design and transformation sequence do it for me.
Animated without doubt.
Also Legends Warpath.
..What? Warpath is a toyline. Or should be. Transformers: Warpath - endless repaints of Legends Warpath. And I would buy them all.
for me its...
- Henkeis
- Master Piece
- Alternity
- Revoltechs
- Animated
- ROTF
- Binaltech
For me it has to be Animated - it's the best, most original and invigorating thing to happen to Transformers since Beast Wars. And does Mutant Beast Wars count as a toyline? If so, then they're right up there too.
