I´ve flown the 140 Cherokee and and Archer II, very different planes but...
If you want to tour 4 up you will possibly struggle in the 140 especially if you are a "fatty"
If you want to poodle around your area the 140 is much more economical and flies perfectly well.
If you a shorty like me the 140 has a much better view out.
If you are a shorty and a fatty then perhaps piper is not the answer for you
