That's not exactly what rejunivated asked!
If you have taken neither airline, then it's really up to you where you are going to connect with the possible flights.
Both airlines offer superior service over other airlines. The only exception I can think of that is a competitor would be EMIRATES.
Anyway, neither SQ nor CX have lounges at CDG that have shower facilities (arrival or departure). SQ departs from the dismal T1 and CX although nicer at T2A, the lounge is better but not much.
The weather has been great lately.
The sales have started too!
