I need to start reading those Fleetway comics. Anyways, when it comes to Archie comics, I think I stopped around issue 53 because I lost track on what comics and side-comics I should be reading. But my two favorites are very close chronologically. One of my favorites is the Mecha Madness Special Issue. It's quite the epic battle between the two robots.
My second favorite is the comic that happens afterward which is issue #40. This comic is just plain hilarious to read. Everyone loves a funny court scene (especially when Antoine is the prosecution).
For the IDW comics.....well. I have a weird obsession with seeing a person's loved one become lost in front of their eyes. And I was quite shocked to see IDW do this amazingly well. A perfect example of this is in Issue #22 where we see Cream lose her own mother in front of her and Vector sacrifice himself to protect his friends and passes the lead detective torch to Espio.
