What are your copper tube wall thicknesses?
We measure our pipe OD.
1/2" - 0.91 mm
3/4" - 1.02 mm
1" - 1.22 mm

We always expand copper ( swage ) and have never had too many issues
 
I suppose expanding (stretching) the pipe for making it into a socket is no different than bending pipes with a bending machine, as still being stretched and made thinner.
But what is the cost of 22mm end feed connectors? Almost nothing.
I see one slight advantage to swage pipes that are rising vertical, - you have a vertical top joint only to solder and the solder will flow down easy, as opposed to also having a joint to solder from the bottom.
If you are counting how much solder wire and flux you are saving by using a swage, then you must be on a very tight price

I think 15mm is 0.7, and 0.9 for 22mm, so a bit thinner than your stuff. I'd be tempted to do it on water (it looks good), but only if I could get a squeeze-operated expander. Seen one in books, but not for sale. Can't be bothered to have to start hitting an expander with a hammer while supporting the pipe somewhow.
 
Swage pipe for plumbing and heating. If the copper is good quality then a swaged joint is fine and IMHO looks good. If you have a bender, springs internal and external with different shaped knees to get different bends, and swaging tool then some quite dandy pipework can be achieved. Mind you I am getting too old to do 22mm too much this way !
