We're talking about ODIs here. Facing the new ball in 90% of matches means 4 or 5 of swing and 20 overs with the field up. You certainly don't need a particularly good technique against pace bowling to succeed as an ODI opener - look at Chris Gayle for instance.
Anyway, I don't really see how it's even close between these players, but as Jono said if you think Trescothick is as good as Symonds just because he faces the new ball, then surely that argument would mean that every half-decent opener is better than a great middle order batsman.
