Of the two, I'm most impressed with the MPX-30 and as you can see I've got their gravity fed model. I swapped out the 0 - 100 PSI gauge it came with for a 0 - 60PSI gauge to better see the pressure readings; the gun pressure is usually used at around the 8 - 12PSI range, and the space between pressure marks on the larger scale gauge made it difficult for me to see. A few PSI either way make a huge difference in performance, and each finish works best at different settings due to their viscosity and other features.
I own a Fuji 5-stage compressor and have their T-series, and the older GXP-C and touch-up gun. I find that I'm using the MPX-30 more than any other gun, but also like the convenience of turbine guns.
Sorry for the extra detail, but I though it'd help you out.
