Assuming you've not seen either, I would be interested in reading what you thought about them.
Sonic the Comic (UK one. Often referred to as "Fleetway") should be available online quite easily these days and I am 90% sure the rights for them have slipped away and no one would be making profit off of them anymore, so I doubt it would be legally or morally grey for people to be hosting them online.
Archie ("Sonic the Hedgehog", and it's spin off, Knuckles) however is in publication and digests are being released with all the back issues (available at your local Borders) so I suggest buying those.
However, I have a sneaking suspicion that you have no intention to buy or read either and were just posting for the sake of posting.
That seems to be his main motif.

I intend to read them both, to go see how I feel, I'm just waiting for the right opportunity, and no I wasn't posting just for the sake of posting here, since this is not the SPA.
