I used White Labs exclusively for many years. I actually loved their old capped tube containers, fortunately I saved dozens and still put them to good use.
That being said, more recently I much prefer the Wyeast smack pack advantage, where I know for sure days in advance whether my yeast is alive or whether I might need to buy some more. So now if I can get Wyeast at a good price (they are all competitive now), I'll tend to go that direction for my liquid yeast needs.
And THAT being said..... I still find the dried yeast advantages to outweigh all this, and I use dried yeasts about 90% of the time. Sometimes there just isn't a good dried yeast available though, so then I'll get liquid.
On a recent batch I bought White Labs, so I still get whatever is fresh and available. But given two fresh packs White Labs vs. Wyeast, I'll tend to lean towards Wyeast now.
