Not only is Countdown one of my favourite characters overall, I like to consider the new mould as representing a kind of
trans-tector chassis, which would house the Micromaster form within the chest (similar to some of the characters shown in the Japanese series
Masterforce and
Victory).
And he even comes with the starship (which I call the
Audentes in my fiction) too!
But then, I am not sure I could advise regarding which is more collectable - other than describe which character is more appealing to me...
...and of the two, there is simply no contest.
(Now, if only Countdown would get himself shipped to TRU stores in Ontario...)
