That's a yes, yes, and a yes.
The tooling, especially the good (=expensive) ones, are the biggest put-off from useing ferrules. I think it's fundamentally better than soldering as when done correctly (=crimped once!) it produces a cold weld joint. The downside is that the ferrule is bigger than the bare wire.
There many places where solder causes problems. Radio amateurs will be aware of the loop aerial made from copper ef or sr plumbing fittings; they melt with high transmit power. Melting and electron migration effects in solder are also likely if used with contactors or circuit breakers that get fairly hot in normal use.
