I'd say for longevity and portability use own custom domain. Simplelogin, addy support using own custom domain. Its just $10-15 something per year. Most tld allowed max cumulative renewal up to 10 years so $100-150. Setup a yearly calendar reminder on January to renew +1 year so at any give time the domain will have minimum 9-10 years before expiring. If got hit by a bus tomorrow then 9 years should be long enough time for whatever accounts linked to the domain to rot and be useless for the next domain owner.
