I have used both slicehost in the past and linode and can't complain about either as both were great experiences.

However, last month I moved several of my websites from LayerShift, NearlyFreeSpeech and WebFaction to DO (over the years I had collected family websites and side projects on different hosts). It took just over an hour to configure the droplet and transfer everything. I'm using a $10pm instance, saving me literally $100s a year compared to what I was previously paying. Admittedly most of the websites receive little traffic, however, I also have planet-tolkien.com on the drop which receives 20-60,000 uniques a day – the droplet barely notices. Thumbs up for DO.
