I have both.
It is more comfortable with the sleeve, and seals much more easily.
The sleeve does not fit the LA cylinder very well.
The gauge-pump that LA sells is much better than the gauge-pump that Boston, or Kaplan, et al., sell. But one can also buy a brass mity-vac pump with a guage elsewhere for less than LA pumps sells theirs.
The wet dry pump that Boston sells is a work-horse.
I don’t know why a one piece cylinder is any better. I will say that the acrylic that LA pumps uses for their cylinders is a better quality for our purposes. It is designed so that if it shatters, it does so with out any sharp edges. So there is an extra degree of safety should something catastrophic happen.
That said, I’ve used the Boston cylinders I have more and haven’t really felt like I’m at risk. :)
