TSOP is good. I remember someone on the Megadeth boards calling that 'The Sound of Self-Indulgence'. I still laugh at that considering it's somewhat true, but it's still my second favorite Death record.
Purtenance is great OS finndeath. I am just checking out the rest and since 2/3 of them are brutal death, I probably won't like them. I am just listening to Apocalyptic Visions right now and the sound like competent DM but nothing that is really sticking out yet (granted I haven't even finished one song yet).
