Merb has grown so large, I think at this point Sinatra is better for very small projects. Use Merb if you want something like Rails, but with better internals and more flexibility of companion technologies. I see Merb as being like Postgres and Rails like MySQL. Both are good products. Merb is better put together from a technical perspective, but doesn't have the mindshare that Rails has. This means less plugins being created, and less search results on Google for your error messages. For advanced programmers this usually doesn't matter, but for beginners it makes Merb much less accessible.
