I went for a manual valve system for problem-free simplicity. They are likely all the same, just quality of compressor and quality of the bags would be your biggest concern.

I'm skeptical of solenoids in winter, hence the manual valves.

When the novelty of the valves wears off, if I still want air ride, I'll likely switch to rig height-control valves; they are pretty affordable and reliable.
