Tip me one good e-reader on Windows 8.

I want you, who read on your Windows device, to tell me one good option to read EPUBs on Windows 8. I use Kobo to buy and read by the way, but... I'm studying Editorial Pruduction and I have to create epubs as well... but all I see is the attention on the iPad and Androids, so nobody can tell me a good option to test my creations (sad, but I'm the only one who fight for Microsoft on that place).

I already used

But I didn't feel confortable with any of them.

So, do you have any suggestions? (I also accept suggestions for Windows Phone)
