I think in either case a cost of "Kilz" sealer is always called for, followed by your choice of interior latex
paint.
I have done repaints on both types of surfaces with good results. I have even painted over wallpaper coated paneling the same way with good results.
The ones that I have seen that look like cr@p, without exception, did not use a sealer coat first. Kilz is the best.
BTW: Reno is a city in NV.
