I use Engine Yard for an e-commerce Rails app. Deployment is simple with a post commit hook. I simply commit and push to Github and the rest is done. You are on your own unless you fork over at least $250/month for a support plan though. I've used Heroku for smaller Rails and Sinatra apps. For my Windows Dedicated running some .NET apps and a Linux VPS for a few Wordpress blogs, I use Liquid Web. I feel they are better than most hosts as far as speed, support, and reliability but not yet a Rackspace. I use Amazon Cloudfront for content delivery and S3 for backups for all of these sites.
