If you order direct from DigitalOcean you'll have root access and you might break something so it's better to order from Cloudways so you'll have no root access and limited control over your server.Never heard of it, but I'd rather just go direct to the source and order direct from DigitalOcean, Amazon, or Google Compute myself. But maybe that is just me.
TO further clarify , Im not a beginner , and im not looking to use them. Just wanted the opinion of the community. Never heard of them before, it seems the key of their service is the management. Good to know about another managed provider just in case a customer need a managed service and want something different.They are basically a reseller for providers, it resells from like three or so providers, I don't recommend it.
I'd recommend going direct to the provider as @MannDude said, there are many tutorials and providers such as DigitalOcean that provide basic help regarding certain features of the server.
It's good for start up companies that don't know much about servers as like @DomainBop said, they don't give root access to the server so you can't ruin the server trying to figure something out.
