I agree entirely with Keith's observations. If you want a plane for reliable transportation from one point to another, a 150 or 152 definitely isn't the plane you should choose. But if your goal is to enjoy the journey, I find it ideal. It's too small for people who fly with a family and not very practical if you live at a hot, high altitude location and/or have to carry a lot of weight, but otherwise it's really hard to beat. I looked seriously at a 150/150 as a way to solve what I consider to be the two main shortcomings of climb rate and hauling capability, but for me the change would have been a step backward in nearly all other respects important to me so I decided to stay with my standard 150. But just like the engine choice I made, other peoples' requirements, goals, situations, financial restrictions, taste, and a lot of other considerations makes my choice best for only me, and not necessarily for anyone else.
When I've spent three days to fly from Oregon to Clinton or Oshkosh (or gone on a 13 day tour of the wonders of the Southwest), I've thought when I landed how glad I was to have the plane I do. The trips were great fun, like a road trip, with lots of interesting challenges and experiences. I wouldn't have had any of that if I had flown in a fast plane, high and above the weather, and in fact I wouldn't have bothered going at all. When I want to just get somewhere, I fly commercial. When I want to enjoy the trip itself, the 150 is the way to go.
