Same for the hardware. they are the new kids on the block. For now it's the newest and shiniest but long term lets see how they keep pace. Linode's been around a while and done a good job of dragging all it's customer's along to newer hardware.
I'm not seeing how this is a record superior to Linode. That said, I use DO due to its price point for hobby/testing projects and dropped Linode completely.
