That's a nice setup too. But I really like arb twin compressor's speed, compact size, cooling fan for extended use and internal pressure auto shut off.
The only place ARB wins IMO is size but you give up the ability to run tools.
35" 14 -35psi - 2min at sea level. ARB is maybe 10 sec faster for almost twice the cost
I have ran mine non stop for 4 hours 100% duty cycle
Puma has a tank to run air tools
I have run a PUMA since 2007 with 100's of hours of run time without any issues.
Do some research and ARB twins have had there share of problems
