I would like to add 3 people, who i used to play a lot and another one i played just few games with, but were the best ones (our only 2 games vs DT - we won the first and got d/c the second:)). Here's the list:
yodarkore - probably the best Vasari player i had the honor to play alongside. Very adaptive style, very agressive opening, very stubborn player. One of the few players i had played more than 25 games and haven't lost any.
ReborN - he was the first really good player i encountered when i returned to SoSE after the "Space ponies", "GE" and LRM rush early months of the game. Remarkable Advent player, who always presses the opponent. One of the founders of Brothers in Arms with me and King of Kings... I don't remember a loss playing alongside him too, that good he is.
King of Kings - co-founder of BiA with me and ReborN. The idea to start a new SoSE team was already shaping with my head, after few days of playing with ReborN. But King was the one who gave the decisive push to it and so that is how BiA was born. He is the most dedicated TEC player i have played with. And one of the best. At the time i used to play he was really famous with his early kodiak tech and if you couldn't stop him, you would lose. Besides that was very innovative when it had to. It was him who i played with, against a very unusual team - ADT Ravok and a DT member (i think it was Tyr) and we won.
The last one i would praise as an exceptional player is Berzerker - very, very strong player. I would rank him alongside the likes of Haeso and King Mike i used to play sometimes in the past. Could be an integral part of any other team that would stand against DT and win.
There are few more, but they had been mentioned already in the postings above - Raknor and Cykur - both first class players, whose skills in SoSE i admire.
