What are the benefits of mining rvn

I am new to the crypto world and looking to get into mining. I’ve been going around in circles because it seems like mining eth is much more profitable on the same card. Are there any benefits of mining rvn other than it’s cheaper to get started. I’m looking to start out with just one card and the Radeon VII is looking like the way to go. It has the best hash rate on what to mine (other than the 3090) and is cheaper than the 3080. Thanks.
