I searched for this information over the years and now that I have all 3 I ran a test. I am putting lockers in my 40, so rather than buy a compressor for the lockers and another for the tires, I bought the twin and mounted it under the seat in the cab
Tires are 34" Toyo MT's on my 100 series
used the same Staun deflater to air down to 18, verified with same gauge each time
Used same hose and inflater/gauge each time
I did not count the time I stopped airing up to check the pressure
Each air up was from 18-42 psi and in my driveway under the same weather conditions
For the ARB and Puma, I waited until the compressor had cycled off to start filling the tire
Powertank 10lb tank and Regulator - 1 minute 16 seconds - Mounted in my 100 series
ARB Twin Compressor (No Air Tank) - 1 minute 55 seconds - Mounted in my 40 series
Puma withy 1.5 gal tank - 2 minutes 18 seconds - Stand alone hooked to my 100 series battery
The Powertank is $510 and then about $10-$20 each fill up. Fast, but need to remember to keep it filled
The ARB Twin costs $500 for just the compressor. You have to buy the pump-up kit for tires and the manifold for lockers. Only the $30 pump up kit cost is relative to this, so $530 and never having to worry about filling up the tank
The Puma is less than $300 and some hard mount it in the truck and you never have to worry about filling up a tank
All 3 of these times are fast if you have ever used a smaller compressor to air up your tires which is closer to minutes to do what these did.
To me, if you are installing lockers and need to buy a compressor anyways, the ARB Twin makes sense as long as you mount it where it won't get hot (not engine bay) that cuts down on performance. The cost of an ARB air locker + one of the other options is what makes this a good call.
If you already have the air locker setup or don't plan on getting one, then the Puma provides great value and performance for the price. With the air tank you can run power tools on the Puma. You can add a tank to the ARB for additional cost.
I know you can also use the Puma to run air lockers if you wanted to go that routes
Some prefer C02 and that's ok, I have run CO2 for 14 years. Filling it isn't so bad, I always get annoyed when it is time to certify the tank and you have to make another trip to get it.
I wonder what the ARB Twin with the 1 gal tank does performance wise?
EDIT: Based on the Twin Results, I bought the ARB Twin Kit with the 1 Gal tank and posted the results below
I bought the Puma to wire up and remove the power tank in my 100 series. So far I have been carrying both along with the ARB compressor for the lockers. I am wondering if I swapped my existing ARB compressor for an ARB Twin if that would work to carry less gear.
Here is a thread on the PUMA showing long term performance and installation options
This would be a great place to post up your results to have performance data in one place.
The Configuration
Tires are 34" Toyo MT's on my 100 series
used the same Staun deflater to air down to 18, verified with same gauge each time
Used same hose and inflater/gauge each time
I did not count the time I stopped airing up to check the pressure
Each air up was from 18-42 psi and in my driveway under the same weather conditions
For the ARB and Puma, I waited until the compressor had cycled off to start filling the tire
Results
Powertank 10lb tank and Regulator - 1 minute 16 seconds - Mounted in my 100 series
ARB Twin Compressor (No Air Tank) - 1 minute 55 seconds - Mounted in my 40 series
Puma withy 1.5 gal tank - 2 minutes 18 seconds - Stand alone hooked to my 100 series battery
Cost Considerations
