@homegrown They are definitely not all the same. I'm experiencing the pain of this right now. I'm trying to get #Nextcloud up and running. I first signed on with a service that seems to be a favorite here on Mastodon. They are incredibly unresponsive. Although they were quick to respond when I pulled my services and asked for a refund.
Now, transferring the domain is a PIA and may not even be possible given that it is under 60 days old. So, that's about 8 - 10 frustrating hours and 30 bucks all tolled for a useless domain and transfer attempt.
TLDR; Use a Nextcloud promoted partner to host your Nextcloud.
#Cloudamo is very responsive (within minutes, not days) and helpful when it comes to Nextcloud. Can't speak to more of their services as I haven't used them, yet. Stux was not. I'm frustrated and probably out 30 bucks plus the domain I was hoping to use for my Nextcloud instance.
