Just my two cents. I owned an Archer for 10 years and belonged to a club that had a couple of Bonanzas (straight and V-tail). I bought a Mooney a three years ago (M20J) and can tell you my thoughts:
1) Pleasant to hand fly. Mine flies wonderfully. But they are hand built machines, and no two fly exactly the same. Mine loves to fly, but doesn't like to land so much...(see #2)
2) I read everything (like you did) about proper speed on approach and thought I believed it. After a few approaches that I flew way too fast I understood it.
3) My first landing with a Bonanza surprised me, I didn't realize I had touched down. It was that smooth. My 150th landing with my Mooney surprised me. It was that smooth !!! (O.K. so it was really my 150th landing...)
Seriously, I wonder if other Mooney drivers can routinely grease it onto the runway every time or close to it. I can land smooth enough for my passengers to say "Nice landing" but I can't consistently grease it on like I could do with the Bonanza. And with my Archer, it was point it at the runway whenever you think about landing and you'll be fine. Not so with the Mooney. I figure 3 miles a minute, 500 fpm descent and pattern altitude 5 miles out. So if I'm at 8500 going to a 500 foot field, I figure I have to lose 7000 feet to get down to 1500 pattern altitude, so 14 minutes at 3 miles a minute, 42 miles plus the 5 miles---start descent 47 miles out !!!
