Indeed, but the problem is putting them in... (without leaking everywhere)

For the water side, I use end feed fittings. So you need a blowlamp, etc.
Once you've mastered the skills of soldering, leaks a thing of the past.
With wastes, I also prefer solvent weld. For the same reasons.

Are end feed preferred to solder ring?

I prefer them since they a

shorter and slimmer, significantly cheaper, and have slightly less
thermal mass, so heat more quickly. At the end, you end up with a neater
looking job.

I keep decent stocks of end feed, and just a handful of solder ring for
the occasions you have to work with one arm under a floor or similar and
can't hold both blowtorch and solder.

And compared to compression?

They are different. :-)

Again, useful in cases where you can get a pipe dry, or you want
something demountable, or are not in a location where it would be safe
to use a flame.

Indeed - and I have recommended same myself, although it does assume
one has a suitable carrot that's not frozen!

When we had a bathroom fitted the plumbers were clearly instructed - no
hot work in the loft.

We have a thatched roof...

Yup, good call!

There are some quite good copper pipe crimping systems as well now...
