(Edited, see below)Cromulent -- what benchmarks did you use to measure performance? I ran some benchmarks of CPU, RAM, disk, and bandwidth, and found that Linode won only on the bandwidth tests, with a comparable Digital Ocean node performing significantly better on all other benchmarks I tried.
I did the bandwidth tests with
tespeed and the rest with
Phoronix test suite. Here are my results:

It's not a 100% apples-to-apples comparison since my Linode is serving a couple of very low-volume web sites, but I didn't see any traffic at all coming in during these tests, and there was plenty of spare CPU/RAM headroom.
Don't get me wrong -- I've been with Linode for 4.5 years, and I'm deinitely not here to bash the service, but I would like to see what benchmarks other folks are getting on their nodes to see if my results are atypical. My node is a Linode 768 instance, and I've felt that it's been quite sluggish for a long time now, which is what led me to look into Digital Ocean.
Perhaps I'm just on a crowded host, but for $30/month, I'm feeling like the results on my Linode should be better, and Digital Ocean is looking pretty good, performance-wise. I agree with everyone who's said that DO is probably dumping their plans at a loss to gain market share, and will probably end up in the "oversold" category once this catches up to them, but if I can get six months out of them, I can save $150, and that's not chump change. I doubt the service will measure up to what Linode has given, but I just can't pay a 400% premium for slightly support response time and more honesty about bandwidth numbers. Perhaps if the performance gap was 2:1 instead of 3:1 or more I could do it, but as things are, I'm going to at least give DO a shot for a month or two to see how reliable it is, and if it stays solid, I'll definitely be considering a switch.
EDIT: I originally just ran the disk write numbers, but upon further review, Linode does significantly better on reads. I updated the charts with a breakdown of sequential/random reads/writes.
