I dunno, maybe. England are possibly a more cohesive team, but then its really hard to judge based on either sets of qualifiers.
Wouldn’t necessarily trust Martinez, but then you could’ve said that about any number of international managers over the years - I think his weaknesses are probably more exposed over league campaigns, ala Coleman. And whatever scepticism you’d have over Martinez, you’d have to say the same about England replicating any of their qualities from qualifiers/friendlies come a tournament
Instinct is usually just to trust that quality will win out
