I couldn't really answer the poll. I use at least 6 widely different picks regularly and several more that I use on occasion.
Most people don't give a lot of thought to picks, but material, thickness, and size all GREATLY effect the sound and tone of the gutiar. Limiting yourself to a favorite pick is to take a lot of variety out of your tone.
For flattop players who are primarily using the guitar for fingerpicking or chords for vocal backup can probably get by with one style of pick, but if your using your guitar as a lead instrument, you really should explore a variety of picks.
Pat Metheny claims to buy picks by the gross and then filter through "identical" picks looking for the ones that have the mojo and discarding the ones that don't. I'm not quite that sensitive, but I use a lot of different picks for different jobs.
If forced to choose an all around pick... I might select the 1mm Dunlop Nylon... but thankfully I don't have to limit myself that way
Years ago I used the hard plastic Gibson or Fender pick, and almost never used nylon picks. But now I find for lead work that I like a pick with a little more traction on the string and different materials have different traction, which results in a remarkably different sound, and nylon works well for this. But again, I'm coming at it from a soloing standpoint. Often for vocal backup (depending on the song of course) I just use my bare fingers which I like more and more over time. Some of my favorite guitar players never use picks.
As sombody said above: I like the Purple Stubby as well for heavier lead work.
