I've flown the Musketeer B23 and the Cherokee 140.
Based on my experience of the 180 HP B23 Musketeer I'd say the 160 HP A19 would be a real slug.
Mind you the Cherokee 140 performance isn't startling either though many have had the HP upgraded to 160 during engine overhaul. This does improve things to some extent.
The early 140's had a shorter fuselage than the later ones so the legroom in the back is a tad tight on the early ones, certainly not a true four seater. Also the cabin door isn't as long on the early ones. If you can get the later 140 with the longer fuselage (same size as the Archer) I would take it over an earlier one. Though with a 150 HP engine, it's still probably a three person aircraft or two adults and two children.
In my opinion the Cherokee 140 has much nicer handling qualities than the Musketeer though that is subjective. One advantage the Musketeer has is it has two cabin doors, well the B23 did anyway.
The Cherokee is probably a better bet airframe wise as parts will be more plentiful.
