Mine RVN, or exchange ETH? Why?

Greetings! If you aren't exclusively solo mining Raven ($luck), why would it make more sense to mine Raven directly instead of mining Eth, and exchanging that to Raven instead?

I did some math,

1xRTX3090, eth@30days mines 0.051eth

1xRTX3090 rvn@30days mines 1380rvn

0.051eth converts to more than 2400rvn.

I'm still scratching my head. Thanks for any advise, suggestions.
