Nothing about the points has changed. No IPv6, no custom kernels, no own OS installs.
Please tell me why you still use Digital Ocean? Me? Just the price. However, I have several VPS's at other providers just to run *BSD or to have IPv6...
That being said I also use EC2 a lot to do things that DO can't, so best tool for the job and all that.
