Which providers has good Roku support and how is the Roku app?

I am currently with Epicstream, extremely happy with the streams and stream quality, but not completely satisfied with the Roku app.

P.S: I have 2 subscriptions with Epicstream, 1 with my Dreamlink and for my second TV with inbuilt Roku. I won't mind trying some other providers on the secondary device Roku if they have a better app.

Epic's Roku app has everything, but it has an annoying EPG bug. When you press EPG, it never shows the current show. It jumps to 6:00 AM always.
