When using compression fittings on copper pipe I've always

make a compression fitting to plastic pipe - more/less/same? My
intuition is saying it should be the same.

If it makes any difference the pipe in question is 15mm Hep2O barrier
pipe and I am connecting to a TRV. Incidentally, I am aware of the
importance of using an insert.

IME, its a similar "feel" to compression on copper.
