As a training aircraft Cherokee 140 and 160 are much better than the optimised for cruise warrior and archer.
Older aircraft pitch down with flap requiring nose up trim, which with experience you van put on a bit extra up trim to assist with the flare.
The warrior is not so nice in the hold off students struggle to flare especially the heavier max wt. 2440 variants and because they pitch up with flap application, too much nose down trim can be applied.
