Whoa now, the fillers from B3 are fine tools! They are well made, sturdy, and work as advertised. The one I used and commented on before was in fact one generation old - they now use a different type of valve for the gas in and beer in, and for all I know now have more control on the gas out. The one I used was a fine machine, probably the current model is even better.
In fact, all of the fillers work pretty well - Beer Gun, B3 filler, Listermann's, poor man's, heck, even filling with a tube shoved in the faucet will work.
Like many things in brewing, it is a matter of what works best for you, and your system, and your methods.
Many people like a little foam generated to purge the headspace of all air, because the foam is all CO2. Beer Gun, B3, and the tube will all generate some foam, but not leave your beer flat.
Some people need to fill a bunch of bottles all at one time, some fill a couple at a time. Beer Gun, B3, Listermann's are all good at filling a bunch because they are easy to hold. Poor Man's and the tube are good for a few because they are quick to assemble and easiest to clean.
Some people don't mind chilling all their filling equipment at bottles, some like to fill warm. Beer Gun and the tube both need everything to be very cold. The other methods can get away with warmer stuff.
Lots of people fill lots of bottles with any/all of these methods, so they all are viable. Again, it's a matter of how you work and what you want to do.
