Better lens option than the EF 70-300 II for an R8 at a similar price and focal length?

Shopping for a telephoto zoom lens for an R8 I recently bought. And I’m close to buying the EF 70-300 II after research and my budget. Just want to see if there was something I missed.

There is the RF 100 to 400 for $650
