For me -- cost difference with no sacrifice in strength/performance. I buy my building materials at Menards. Quick check of price this morning shows 7/16" OSB at $12.05/sheet while nearest comparable plywood sheathing is $13.99/sheet for the lower grade 3-ply 1/2" CDX. If you want 4-ply, it's $17.95/sheet. CDX also likely to have significant voids in it; not so with the OSB.

+1 I agree. The cost difference was significant.

Cost for me as well as I got my sheets of OSB for $10.35 a sheet .... and I did not have to finish the seams.

Mine took 2 coats. White ceiling, light color walls. If the OSB is not installed yet it is a lot easier to paint first, laid on the floor with a long handled roller. You can touch up the screw heads with a small brush later.

I went the airless sprayer route.
FAST and if you work it right the spray will seal the little gaps and voids dust would land in. Good heavy coat or two and a leaf blower will do a good job of moving the dust to somewhere else.

Either plywood or OSB ,plywood cost more. 20 years ago I installed OSB on my shop walls but with the smooth side facing the room. The rough side has the stud lines and is not a factor. I like the rustic look so I did not paint or even seal the OSB. I had thought about painting the walls at first. I have 9 windows and a double door so lighter walls wasn't necessary.
