Just curious, what are you building/launching that requires more than 1GB of RAM at launch? 1GB is a lot of memory for most use cases, guessing something involving graphics or maybe simulations? In those cases, dedicated instances with proper hardware will give you enormous performance benefits, FYI.

Both Vultr and Hetzner are solid options, I'd go for Hetzner if I know the users are around Europe or close to it, and I want to run tiny CDN-like nodes myself across the globe. Also, Hetzner if you don't wanna worry about bandwidth costs. Otherwise go for Vultr, they have a lot more locations.
