In the past i prefered gtk# but now i see in windows winforms it´s 
clearly better. Port your winform application to linux is direct,  but 
in windows if you use gtk# you have all gtk+/cairo/glib dependencies.
Besides in windows with winforms you don´t have any memory fragmentation 
if you don´t want because gdiflat[1] is very studied for that. I believe 
in linux with cairo backend winforms have a little of overhead because 
utf-8/utf-16 conversions and the expensive use of malloc [2]. I would 
like see a real gdiflat for linux or a full native backend in OpenVG.

For me it´s clear we need a mix between the pure c# code with the 
garbage collector for GUIs and code in pure C with static code and 
memory pools or own malloc constructors.
