As someone who just made the switch in the opposite direction (I've been using Mail for multiple emails accounts for a few years) I'd strongly suggest sticking with Gmail's iOS app. My email experience on mobile has been much more enjoyable, Mail was glitchy and difficult to use/organize for me.

Thanks for the info. I may just do that then, or just go with a shorter trial period. Pretty sure I can use both of them at once with no issue.

I'd love to know who and why my parent comment was downvoted.. I hate that, you can't say anything on here without downvotes.

I use the Inbox by Gmail app on iOS and I really love it. I never got into the regular gmail app. Inbox is far better than the standard Mail client for gmail IMO.

If you have an Apple Watch, that is a must since there's no Gmail watch app. Checking email on the Watch is surprisingly useful.
