Hi John,
The big difference between the engines are the cam - a stick 140 has an 891 cam installed straight up, the PG 140 has an 889 cam with a 4 degree retard. The PG engine has a better torque curve down low but gives up 15 HP or so on the top end.
All else being equal, for a rebuild I'd pick the PG engine as it will likely have seen less abuse, and install the cam of your choice as specified by the cam supplier.

Which would you all prefer to use and why one over the other? Thanks in advance for your reccomendations John in NC pondering this age old question!
