How to evaluate hosted CiviCrm enviroments
Much could be said on this (and probably will be!) but here's a few starters you might want to consider. What is "best" for you depends on which factors are important for you.

If you use a hosting environment that specifically supports CiviCRM then things like MySQL version, MySQL permissions, php version, php memory will be ok.  Otherwise, you need to check they meet CiviCRM's requirements which are fairly demanding.

Some hosters will upgrade Drupal &amp; Civi for you.  On others, you manage your own upgrades.

Some provide Let's Encrypt automated free SSL certificates.

Some provide ssh access.  If so, do they provide drush, wget, git etc? (Does drush, wget or git matter to you?)

Personally I'd opt for a specialist CiviCRM hoster.  Avoid a hoster that doesn't explicitly mention CiviCRM.
