Have migrated over to Outlook.com as well and can confirm that the user interface is quite refreshing when compared to the deteriorating state that is gmail. Be aware that Outlook.com is not 365 and there is unfortunately no paid or premium support option, however entire domains are supported via going to domains.live.com. Perfect for family emails/domains, etc.
After migrating I authored a plugin for Google Chrome that makes Outlook.com your default email application and provides a button to compose a message to quickly share a link via email. https://chrome.google.com/webstore/detail/send-from-outlookc... if your using Chrome + Outlook.com check it out.
