For me, an APX is a wonderful tool and I use P25 quite often. My other newer ham handhelds (Yaesu FT3 & Kenwood D74A) have only recently caught up with some of the features it offers. I definitely do not think my VHF/UHF 7000xe sucks. Like most things once you get used to programming it, and learn how to get things done with FPP (Front Panel Programming), one realizes how easy they are to use. Adding a repeater now and then is definitely not an issue, especially with FPP.
Everyone's environment is different. I would not enjoy driving an H1 in single lane neighborhoods in Japan. Hell, it would not fit on some streets, but it is fun to drive in California. My friend has the civilian version of the H1 and it is wide, but I drove it and got used to it. She drives it everyday. Hell, I use to drive a Class A motor home as a teen around town when a car was in the shop. You always had to watch the width, height and your caboose when making turns. It was only 30 something feet, so it wasn't bad compared to the 40+ foot; you just need bigger side mirrors.
Basically, one learns by doing and gets comfortable with it. Overkill for some, absolutely not a problem for others. Training and successfully learning to program, tune and operate Motorola gear seems like a good idea to me. Look at what we would be left with for the amateur radio community without a Motorola repeater, handheld or mobile. In many ways used Moto equipment is comparable to amateur radio pricing. (Not so much on the APX 7000/8000 stuff at the moment.)
I venture more than five feet beyond my property line, so maybe it is just me. I do enjoy having good equipment when I am outside cellular service and hours away by foot to a main road.
