Of course, some here would probably argue you're still getting sub-par overall performance 100% of the time, but that's another story.

However 100% of the time that it's true...
To try to answer spitfire's question, I'm 99% sure that the Nerf SS Switch Shot is the only Nerf SS blaster with a nozzle selector. Many Water Warriors blasters have a nozzle selector too, but they are not the same set of nozzles on the Switch Shot. WW's typically feature two different stream sizes and one 3-stream nozzle or a burst or something similar, and include 3 nozzles instead of 4. WW blasters try to focus on more streamlined, general purpose nozzles that aren't as range restricted, at the expense of not making interesting stream shapes and effects.
I can't link to the specific images even indirectly, so you'll have to search on iSoaker.com for these blasters and pictures of their nozzle selectors. The Nerf SS has one selector, while Water Warriors uses the same nozzles for the Python 2 and Colossus 2, but the multi-stream burst is replaced with a single, larger burst on the WW Avenger that oncoming storm mentioned.
As for alternative options, if you really like fancy nozzle selectors, have a look at blasters like the CPS 4100, CPS 3200/3000, or Monsters series. Monster XL has two nozzles and selectors, with 6 nozzles each and numerous combinations. Not exactly built to be battle practical, (although all CPS's and Monsters series blasters vastly outperform anything available on shelves right now) and if you're a fan of neat stream shapes, definitely worth checking out if you're able to.
