I'm frustrated with Siteground's dilapidated interface. It hasn't changed in at least a decade. Parts are broken, such as Siteground's own login screen not remembering you when you check to box to log in. They have no API to set up client sites, so reselling hosting is a very manual process (one of the reasons we don't outright sell bare "WordPress hosting", and as our list of live sites and staging sites grows, there's no solid organization method (we can't tell at a glance what staging site is for which client, for example).

On top of this, we're running secondary backups via BlogVault, which is an added cost as well.

Because of this, I'm starting to feel like we've outgrown Siteground, despite the site speeds being very good and the support also being very good. We don't have any real gripes about Siteground except for how manual and "hunt and find" the back end is, but we do have growing concerns over the direct costs (siteground), indirect (BlogVault), and opportunity costs (not being able to resell hosting in an automated fashion via our website), as we continue to add additional sites (we have 11 in the works right now).

I'm considering future growth, the ability to automate the deployment of hosting using SpinupWP's API and Digital Ocean's hosting, and SpinupWP's direct integration with Wasabi (which we already utilize for my primary company, an IT business, without issues).

Does anyone have any feedback as to why this would or would not be a good decision? It seems everyone has an affiliate-based opinion on which hosts are the best. Siteground has always been good TO us, but I feel they may not longer be the best FOR us as we look to the future and hope to expand our offerings, staffing, and speed. I was also considering Hetzner over Digital Ocean, but it seems Hetzner caters more to the EU and we're based in the US.

All feedback is greatly appreciated.
