Class vs Variant/Enum in a QSM

[Jeanius]

I'm wondering if there are performance differences between a class-based QSM and a variant/enum QSM.  To clarify, are there any glaring differences between sending a cluster with an enumerated state and variant into a consumer queue, and sending just a class that dictates what state will run?  Or is it all preferencial?  Are there particular situations where one would work better than the other?

Not that easy to answer.

Steve Chandler has been doing a benchmark Performance of state machine with enum vs string. His target was to get maximum speed of a state machine.

Huh, interesting.  It'd kind of make me think that performance-wise enum/variant would win versus a class, but I'm not sure how reading data from a class as opposed to converting data to variant and back to data again would compare.  Thanks for the link.
