I believe that it is better if you have more platforms. For example, I have a Linux, and there is a lot of Windows-only submission I cannot check. Usually it is not a headache to export it to browser, so I would recommend you doing it. I believe you get more ratings in that way -in this way it works in every OS and it may be accesible to mobile!
We exported our game to browser, Win and Linux, since we had the possibility to do so. The HTML5 exporter is not 100% reliable (it gives us some music bugs sometimes) so having also the native exporters is a good idea also!
I leave the game here in case you're interested in it :D
