Ceruledge is better on Speed and Attack while Armarouge is better at HP and Defense

I would say it's a tie.

Yeah, they're both equal. Ceruledge is faster and has better Attack and Special Defense stats, while Armarouge has better Special Attack and Defense. I'd say it depends on the matchup and team you're facing against

Which ones the red one?

Ill go by looks

Armorouge is the red one.

Also Armarouge is having more success since I barely run into Ceruledge on showdown/see it placing top in tourneys
