CSeries (A220 now!) is C*U.
The easiest way to describe it is it feels like a conventional aeroplane.
We use a preemptive trim technique when accelerating or decelerating so rather than holding an increasing force on the sidestick and then trimming it all out at the new speed we nibble away at the trim as the speed changes. If done correctly then no force is required on the stick at all. It may appear to be flying on trim but really it's flying on zero stick force enabled by trim inputs.
