I've only brewed a handful of lagers, using MJ Bohemian, MJ Bavarian, W34/70, S-189 and WLP802.I have some diamond, but I haven't used it, yet. I also brewed with WLP029 when I thought it was an ale yeast.
What I want from a lager yeast: clarity, cleanliness, relative dryness and a touch of sulfur. That small touch of sulfur, for me, makes a beer taste more like a genuine European lager. Every lager I brewed came out fine, but when I split W34/70 with S-189 in a largish bohemian pale lager, I decidedly favored the 34/70. I never got any sulfur, fwiw.
