I've been enjoying the new Archie Comics Mega Man series although it is definitely one of the lighthearted comics moreso geared towards younger teens and the first arc is a super basic story. But for me it is pure nostalgia and I can enjoy it being a long time Mega Man fan. I am hoping that the next arc which starts at issue 5 will be a bit less "simple" and a bit more "impressive" but if it keeps the current tone and story archetype then I will be fine. For me it is an enjoyable nostalgic read.
I haven't checked out the Sonic comics that Archie has but they seem to be going for high numbers like in the 100s or 200s in terms of issue numbers. So I'm guessing that is good or doing well don't know I've never been a Sonic fan.
