Best mobile total war?

Looking for some advice on which one to pick up. I have an iPhone 13..

Medieval 2 was my first total war and the one that got me into the series. I love it.

I haven’t played the original Rome but heard it is a classic.

Which one holds up the most? I have put in hundreds of hours in Rome 2. I’m not sure if Rome 1 will feel ‘outdated’ because of it. I know what to expect when it comes to medieval’s mechanics.

For those who’ve played the mobile versions.. are they easy to play with touch? How is the accessibility?
