For what?

Indeed. That would be a very good question, before you can correctly
give an answer.

I am going to make a guess at the answer.

I don't know any hobby where it is common to solder 10 - 22 wire. BUT! If it's a typo and he meant 18 - 22 wire, and specifically talks about blade type connectors, then he's probably just doing automotive. And he's right, the cheapo connectors available can be a problem.
a proper crimp connector, finished off with shrink tube works fine.
Thise cheap pre-insulated crimp connectoes are basically crap. You
need a "proper" crimping tool to do the job right with the
non-insulated crimps too. There are insulated crimp connectors that
work well with ptoper crimpers too - they have a shrink sleave on
them. Most also have a low temperature solder bead in them as well.

The Philips Sta-Dri system is very good if used as directed.
NTE is another supplier (available through Summit Racing)
NationalStandardPartsAssociates" Sealed Crimp" connectors are also
good. ANything with a butted seam barrel is "basically junk" - a
brazed seam connector is a quality connector that can be crimped to
solid or stranded wire.
If you just need butt connectors Tyco Gardner Bender makes "solder
grip" butt connectors and they are available from Home Despot in the
USA but not in Canada (what else in new?) They are,
however,APPARENTLY available at some Canadian Tire stores. They
install with a heat gun.
