Not really, no.
For many manufacturers the 15A and 20A outlets are identical except for the plastic face plate. They literally use the same brass behind the plastic, down to the T shaped connectors.
Fact is 15A outlets have to live with the possibility of being on a 20A circuit, so they are built with that in mind.
It's a weirdness of the NEC that they expect you to run 20A circuits to multiple 15A outlets.
Get a good 12 Gauge cable, no matter the connector on the end.
