Paint Sprayer...?
Answers: Total time will be less near a roller. More masking and cleanup time is required beside an airless sprayer.
After applying multiple thousands of gallons of paint,,, take the time to brush and roll. You're conversation about an nouns likely smaller amount than 300 sq. ft.?
Interior spraying is great in a exotic house, unfurnished, with no runner or woodwork to mask, but contained by an existing interior it isn't something I'd recommend for a DIY. No offense. The prep time alone might discourage you, as would overspray possiblitities, even with an airless. You'd almost hold to hermetically seal those areas to avoid OOPS, and after concern with flooring, furniture departed behind, window, etc.
Just one old man opinion, but I've be at this a very long time, and would never spray and interior as a fix for not wanting to brush and roll within a house being lived within.
Obviously airless is best for even exterior work. WAGNER,,,you could probably forget. Airless, siphons paint direct from a can or bucket, usually through a length of hose, without a entail to have a POT attached to the gun. It still uses a vacuum of sorts to draw and spray the paint, but not a compressor that creates AIR driven spray through a gun that sucks the contents from a pot attached to the gun. I promise you it still includes OVER sprays of a sort.

In essence it's a personal choice for you. I suspect however that brush and roll would allow you time to relax after/longer contained by the rooms, without the extreme prep work added to the drawing, then wearing clothes cleaning of the spray equipment. You can always throw away brushes and rollers; drop cloths and video..
Pros- This is why most painters love them it is because they uses partly as much paint (which puts more money it their pocket), it is suppose to go faster and be smaller quantity work.
Cons- After you spray the paint you are suppose to brush over the paint or roll over the paint to prevent runs and streaking, and less wall showing. Spray sculpture lasts partly as long, since it uses half as much paint. Most sprayers are made for pro painter that use low priced and low quality paint, so commonly times sprayers don't work as well when using large quality, soaring solid paint that lasts. A hose down down paint will often come sour of the wall within a couple of scrub versus something like Top Secret Coatings lifetime interior that starts to show wear after two thousand scrub. Huge difference.
Good luck.
diy docs right you will end up beside over spray on your stuff as far as using less paint that's not why the pros use airless sprayers it's because of the shear speed of application of the paint
