I fly both types on a fairly even basis. I'm convinced from the actual reaction of friends, family and prospective passengers that the biggest single factor in PA-28 sales has been the appearance. "Oohh, it's just like a real plane" I can hear them say.
I've had that
Both my Dad and my best friend (who both recently flew with me) prefer the PA28 due to its looks.
I conclude from all of this..
Trips into short strips with aviators = 172
Longer trips into bigger strips with non-aviators= PA28
I'll go and sit in the 172 tomorrow and check it out then complete my PA28 checkride and book some time with an instructor in the 172.
Thanks for all the very useful info
