Aesthetics does not account for the lack of any way of contacting a Human should you come into trouble.
A prettier GMAIL? Quite frankly, who gives a hoot?
GMAIL is strutture in such a way as not to request "human labour", never.
This makes it very, very frail and user support is, literally, non existing.
If for any reason, you loose access to your account, you are basically fucked.
Lessons learned: GMAIL is OK for basic throw/away don't care type of things.
If you are using GMAIL professionally you are doing it wrong.
First of all set the correct DNS records of a domain you own to point to a service, any service which allows you to set some firstname.lastname@example.org.
Should you not like the mail provider service, you can move your account where you like, and NEVER, EVER loose access to your mail account.
First thing to check if you plan to use a service: is there a way to contact a human being? is there an actual phone number you can use to ask for assistance?
If you can't contact them during sales phase, go someplace else.
