What Format Is Most Popular For DD?

So as you know my upload speed is slow as hell, so to help I'd like to know what format you play it in. Now from Renpy compile options I can have:

PC.
MAC
LINUX
WIN86x
MARKET

Those last two I'm not entirely sure of but some of you might use them. If I know what is the most popular you are waiting on I'll make sure to try uploading that format first.
