I actually like using both. Brewing 2.5 gallons at a pop, for me using either is a breeze. Sanitize the package, sanitize the scissors, give the yeast a little pep-talk...and in they go.
Lots of interesting liquid yeasts for sure, and thanks to the great cross-reference work by dmtaylor et. al., I think I'll be experimenting with some more dry in the near future.
One thing for sure though, I'll always keep a pack of US-05 on hand...in case of emergency.
