Is there any reason I shouldn’t be using Ethanol 94 (E10)?

Since I bought my Yaris (new) in 2021, I’ve been filling it with Premium 95. I’m not a car person, and my parents both told me I should use 95 to take better care of it, being a new car as opposed to the shit boxes I drove before this.

I’m now starting to think this isn’t necessary. I’ve just checked my fuel cap, and it says E10 is fine.

Is there any reason I shouldn’t switch to E10?

Thank you for any advice you can give! :)
