The interesting question isn't whether it's "more strict" (I don't
know how you'd measure that objectively).

GPLv3 does contain requirements not in GPLv2, which is the test GPLv2
makes when it grants permission to redistribute "under the terms of
this license".

Yes. This is what the GPL creators aimed to avoid by recommending GPL
users to use the "or any later version" grant of license.
