DigitalOcean doesn't have much Asian presence, Linode's backup doesn't support non default file system like zfs, DO / Linode don't have HDD block storage like Vultr does (which I think is a hidden gem you can't realize until you go add one as it's not mentioned in the pricing page) that can be a very nice option to throw backup data in at 40GB/$.
Vultr's CPU isn't as good as the other 2 by the look of sysbench, even for high frequency types.
Those 3 vendors only have 2 or 3 backup slots which can be kind of unreliable if you didn't notice data loss over a weekend and weekly backup can be too far apart.
Hetzner is almost perfect if they have a bit more location. Very cheap, very high performing, daily backup with plenty of slots but no HDD block storage.
Sometimes Amazon Lightsail can be a decent option as they have 7 daily backup slots, free bandwidth is comparable to the others and prices aren't bad except their CPU suck.
