Connection on to orange 4inch soil pipe

[Fallout]

When connection on to an orange 4inch soil pipe to take up a soil stack is it best to use a single ( one end glued) or doubled ended socket?

Drainage (orange) should be push fit joints , solvent cement won't adhere.

Either will do if the pipe is uPVC but a double ended socket will be a bit more flexible.
