Really like Evergrey - have discovered them with their second album, Solitude, Dominance, Tragedy and enjoyed their stuff ever since. My favorite is In Search of Truth... such a great record of dark, melancholic metal. A mini-classic in the genre, for me.
I agree with the general sentiment expressed here that they seem to have comfortably settled in their sound with the last few albums. I mean, they always had a pretty recognizable mood they didn't stray too far from, but if anything they seem to be even more comfortable with it as of late
Especially with that chugging-type of riff they use a lot these days.
That said, I think they have been on a very good roll, quality-wise, since Hymns for the Broken. I can't quite pick my favorite from the last four, although I miss Carina's contributions (has she done anything outside of Evergrey?). I have listened to their latest a ton, this year.
