Hi Frankie,
Don't take the number of downloads as lack of interest. People tend to wait until the result is perfect...
My level of C is not sufficient to play with all your tools. What I have noticed, though, is that copy & paste from VS to Pelles C works fine in most cases, while it doesn't work the other way round. And the problem is VS, not Pelles C. Often it's because variables need to be declared before any code in VS - now I try to do that in order to remain compatible with VS.
I like Pelles C. It is fast to compile and simple to use. If MS standard headers can be used, too, more C noobs might be tempted to try Pelles C first before launching that behemoth of VS.
