In part it should depend on the TYPE of pipe and its application. Certainly a P trap in a sink is fitted well with a top seated compression ring, but I'd hardly expect that at the exit area of a 4 inch sewage drain.

There's no clear cut answer. A lot depends on your skill levels.
Plastic is probably the easiest, but you can't be sure how long it will last before it starts leaking.
Compression fittings are fairly easy provided you clean the copper well first and apply a little jointing compound. They tend to be safe for about 30 years.
Solder ring joints are fine once you've got the knack. You run the risk of setting light to the floorboards. If they don't leak immediately, you can trust them for a lifetime.
End feed fittings are probably the most difficult, but you are in control of how strong the joint is. If it's done properly, the joint will outlive the copper.

It all has to do with application I certainly agree that plastic has brought us into the 21th century as already stated.But as in everything it doesn't meet all situations and i'm going to give one example around extreme heat metal is my choice. So if it is for the purpose of tying into high temps copper may be the better choice.Around the house plastic no doubt. That is plastic with a compression band.

In this 21 st centuary it is OK to use push-fit on plastic pipes, provided the pressure is not excessive. There are many advantages in that it does'nt suffer galvanic corrosion. I remember one case where the copper pipes were being eaten away, we discovered that the electric bonding went to the pipes but nowhere else, so the copper was replaced with plastic, and an electrician put in proper earthing (ground) connections

Ask any quality plumber and solder conections are always the best.
First they look neater
secondly they hold better
thirdly they last longer.
Finally - you can walk away knowing that it will not leak (as long as it is done properly)
Push fit - don't always hold - say your pipe is on a slight angle, it can leak.
Compression can burst.
Have fun

Check out www.npda.co.uk.
Its the national property developers association so I'm sure someone there will be able to advise you.
You can become a member (for free) and ask in the forum.
Hope this helps!

If you are working on copper, a solder joint is the best. Compression fittings are not allowed by code (in most States) in areas that cannot be easily viewed. (in walls and in crawl spaces) Flare fittings are allowed on gas lines (where copper is code) and are usually required on water lines that are buried.

it really depends on the pressure that the pipe will be working at, if it is a low pressure pipe then push fit connectors will do..
The higher the pressure the better the connection has to be
