list your favourite HD release group

I can't believe I didn't reply to this thread yet!

Private group: ESiR for sure. They have become a standard for any of my downloaded HD material. Unparalleled consistency on any/all releases I downloaded of theirs'.

Scene standard groups: CBGB/SiNNERS; they always encode movies properly, and usually add in an extra contrast/brightness factor, that seems to always make the movie look better than from other sources. I usually am very irked when an encoder decides to edit something in the movie to his taste, but those two groups just have plenty of fine taste in what a director would love to see his movie shown as.

Niche HD group: THORA; can't ever complain about their releases. Timely/nice, and now they're even back! :D
