Don't get caught up in the mistaken argument that more psi is better. The Makita wins, no contest.
I'm definitely not! Storage gallons, cfm, & scfm @ 90psi are more important depending on the application and with this application, framing gun, the requirements are substantially lower than painting or using air tools.
How important is weight for you? How much will you have to lug it around. For nailing, a big heavy compressor is overkill.
The oiled makita is a quality unit no doubt, its also 60lbs. This oiless makita is 29lbs. The HD one i have is 35lbs How much will you use it, and have to lift it around?
Go pick some up and walk with them. Decide if you want to save your back with an oiless unit.
If you are a contractor, you need the service life of the oiled units.
The smaller units will run a single nail gun just fine.

Great idea to visit Home Depot or HF and carry the floor models around.
I have at home a belt driven stationary horizontal tank but on wheels, a PC 2 tank 6scfm @ 90psi on wheels if I need to use air tools.
I'm not a contractor nor a young f.t. Handyman, I'm a 68 yr old part time Handyman that just retired from a white collar job whose father was a builder so I grew up in the business that gets involved with power washing plumbing electrical tiling painting carpentry, framing the occasional door, putting together ikea furniture, mouldings, wains coating, chair rails, hanging mirrors but I've done installing in wall med cabinet, bathroom vanity, I've done kitchen cabinets but it takes so long for me, so there is a need for a very portable unit. I've "towed" my PC, borrowed a friend's very light oilless Craftsman, that's what got me thinking along with the heavy PC.
I am the last guy to rate a compressor on a psi rating CFM was listed also 3cfm at 90psi. In this case and its intended use DIY just to drive a few nails with a framing nailer it's up to the task and deliver air for the task. PSI rating was give as it will give extra tank storage capacity before its running directly on the pump it never will in this application..
1 I like the Makita for day in and day out use on job site for this application is it really needed???
2 the Fortress comes in at 20lbs lighter could be nice for older gentlemen lugging around.
3 Fortress matches db rating and claimed CFM are very close 3cfm for Fortress and 3.3cfm for the Makita both rated at 90psi.
4 Fortress I would bet is about 100 dollars cheaper.
5 it's not my decision its only a option and one that will do the task without any effort I am not recommending this for any other task as non were given.
I've always felt spend a few dollars more and have less problems and more satisfaction performance. Husky Kobalt quality is fine with me, some HF is fine not their hand tools other than their new Icon line. I want stuff to last that's why the hesitancy with HF oilless ($130) and the leaning towards oiled Makita, Emglo, Rolair in $225-$275. Oiled lasts longer but do I need that? No. I'm just afraid oilless HF will die before I do. Using it day in and day out won't happen! It will sit for months at a time. Others using it won't happen! I just always so much feel more comfortable and secure with quality, definitely not an ego thing though, just longevity and performance.
