I have personal experience with the Makita air compressors, especially the MAC700. I had a big issue with it when it first came out which supposedly helped Makita re-engineer it. The crankcase built up too much oil pressure during pumping and the outside would quickly become a mess which led to leaking on the surface that the compressor was standing upon (and you better hope you didn't screw up someone's nice floor). It was too heavy for a compact portable, I felt. The weight is due to the construction quality of the compressor. The only thing I didn't like about it in use, other than the oil issue was the movement. It's not balanced internally like my Thomas compressors are, although that's one of the reasons for the big price differences between most other compressors and Thomas. I can't stand these hotdog style, tall, skinny compressors that easily tip over, whether it's from pulling on the hose or while traveling in your vehicle.
The other model Makitas are too heavy for general trim or punch list use, in my opinion. I like something with a low center of gravity to eliminate the tipping issue I referred to. I also prefer oillless so I don't have the maintenance, temperature on viscosity issues and potential for oil mist on the work surface or surrounding area. I think a maximum of 30-35 lbs. is good for getting to and from or around jobs, especially when traveling up and down flights of stairs. I used to deal with my bigger wheeled compressors up and down stairs, but came to the realization that those are ideally for framing work where you need the added cfm air output for multi-gun use and rapid nail firing. The small compressors are usually just fine for providing enough cfm per shot for finish, brad, pin and staple guns or the occasional use of a framing gun. Just make sure the pressure stays high enough under typical use or you'll be countersinking plenty of nails. That's the one thing I like about the Porter Cable compressors. They have a cut in/cut out pressure of 120-150 psi., so when you've got your regulator set to give around 100 psi to your nail gun, it'll keep sinking the nails even when the tank pressure goes low. Most compressors are set to come back on at 95 psi and shut off at 125-135 psi. I try to adjust them as high as they'll go while not triggering the blow off safety valve. Read the compressor's warnings and stamped setting on your valve before contemplating doing this.
My big compressors get less use now, but you can't beat that higher cfm and bigger tank for blowing dust off stuff. I especially appreciate using my Thomas and Dayton compressors with their 100% duty cycles for blowing out entire rooms of dust or my truck, where I'm doing it for an extended period of time. Typical compressors are 20 minutes on and 40 minutes off or 30 and 30 for a 50% duty cycle. Any more than that and your compressor will have a short life.
Also important on any air compressor is to make sure your air intake filter stays clean and dry. Frequently blow them out backwards, opposite the way they take in air and replace them when they are too far gone.
