I do both C# and Ruby on a regular basis, and well even with all the sugar, for most of the job, C# is nowhere as concise as Ruby. I started using C# in 2001 and Ruby in 2004, and even after several years, I find I'm a lot more productive using Ruby. This is my main reason - I can tackle projects with 2x or 3x less people on the team (which means I can also tackle alone projects vs. building a team of 2 or 3). As well, I find dynamic languages more "fluid" to use.
