To the OP:
If you decide on the 140 you'll have no trouble learning to land it consistently, and you won't miss not having the semi-tapered wing.
If you decide on the Warrior you'll have no trouble learning to land it consistently, and you won't miss not having the Hershey bar.
Back seat passengers in a Cherokee, any 4-cyl Cherokee, are second class citizens. If they have legroom they should consider it a bonus, and avoid bitching. That's just a personal opinion. Your spouse may feel differently, and you should listen to them instead of me.
The older planes are lighter partly the smaller fuselage, partly just less shzt in them (my 2200 lb gross weight 1961 was so light it had a 980 lb useful load). 10 extra hp and a lighter airframe would be my pick. BUT if it doesn't have the baggage door, that could be a PITA if you plan to do more than burger runs with it.
My credentials (since we seem to be into that sort of thing)? Owned and flew 4 different Cherokee derivatives, an original 1961 160 (they were all 160 hp to start with), a 1976 Archer (semi-tapered), a 200 hp Arrow and finally a Dakota, before I bought a Piper twin. Each was "the right airplane" for me at the time, and I loved owning and flying all of them.
