Re: Cobol
I haven't looked, but my reason for C# over VB - besides the nasty taste left over from VBA, is that I came from the Java world, C# was a natural move. I imagine you'll find Java and familiarity is more the cause than "braces look cool".
(p.s. I started in Object Pascal and Delphi 2, and found curly braces weird and distracting for the longest time).
