I have been using Silo for about a year (at a beginner's level, 3D's just a hobby for me...), but I almost didn't use it since I bought Hex. The workflow is much faster, and I find more user-friendly. I must admit however that there were a few features in Silo that I miss in Hex such as the possibility to "flatten" selections, and the topology brush, so I sometimes do an export from hex to refine topology, and then go back to Hex. The major feature in Hex though, is the dynamic geometry, that really helps!
Both programs are very good, but the price difference is justified for Hex, and I'm not saying because I'm on an Eovia forum...
