40mm waste pipe - solvent weld or push fit?

[Possom]

With regards to 40 mm waste pipe, I noticed there are two different varieties available. These are the solvent weld waste pipe, and the push fit waste pipe (links below). If using these under a bathroom floor, is it generally preferable to use the push fit, since it is quicker, no solvent is required to be purchased, and the piping is cheaper?

Or is there any particular benefit to the solvent weld pipe? Thanks.

Solvent weld every time but especially where its concealed. A properly made solvent weld joint in permanent whereas a push fit joint can be pulled apart or forced apart by pressure. I don't know of a single professional who would use push-fit waste. Garbage designed only for the diy market.

Solvent is so easy. Dry fit everything, mark up with a pen or similar, then glue and align all the previous marks. I cant think of a time when i would use pushfit.
