Which NL service do you use with Ghost? Sendinblue, Mailchimp, Mailerlite?

I’m trying to decide which list-building service to use with my Ghost site/s. At the moment I’m looking at SendinBlue, Mailchimp and Mailerlite. Curious to see what sort of experience you’ve had with any of these (or others I haven’t mentioned). Everything from ease of integration, ease of use, features etc.

Any opinions, experiences or nuggets appreciated.
