I actually picked my Liberty over others because it didn't have a rear disc or liquid cooling. I wanted as simple as possible for my daily commuter, but I didn't want another carburetor.
Your simplicity model is also mine. I wanted air-cooled and fuel injected. For a scooter this size, and limited speed, a drum on the back is fine...especially with ABS on the front.
I eliminated the PCX because it has to be almost completely disassembled just to get to the valves for adjustment. I eliminated the SMAX for much the same reason. While less bodywork needs to be removed (than the PCX), if you follow the manual for adjusting the valves you have to remove the water pump to gain access to the timing marks. There are ways around this, but sort of hanky.
Water cooling is on both the PCX and SMAX...and I think it just complicates things. More to breakdown. Air cooling is why I drove VW's for years.
Fuel injection, while more complex by many factors than a carb, is finally at the point where it is very reliable. And, you get the optimum air-fuel ratio under changing conditions (altitude, temperature). If these systems were still like the FI on my 1968 VW Squareback (that I removed and replaced with dual carbs), then I would avoid them, but they have come a long way in 53 years.
