Not sure which is better, but we installed a Rapid Air system in new shop. Used their 1" product. Made a complete loop @ the top of 20' ceiling walls. Drops come straight down the side. Great folks to work with. We did have one outlet that had a crack & was leaking. It was defective on the back side. We called Rapid Air & they apologized & had replacement sent out no questions asked the next day. Never got put on hold @ their phone....they're good. Connections are easy to do.

The biggest problem we had was back at the origination point which is the compressor over 100' away. Used 1.5" steel pipe fittings direct from China & have had a terrible time stopping leaks. This has nothing to do w/the Rapid Air product, but rather steel pipe prior to the Rapid Air. We have a BIG pipe wrench too!

Here's photos of recent Rapid Air install. More photos here:
