Neither. You should be buying a airless sprayer. With the other guns you will need to thin the latex too much.

Ya, a roller would be a better choice. Cup guns [and pressure pots] are only for spraying thin coatings and work best when the coating is solvent based. Latex paints would have to be thinned too much for conventional spray and the air that passes thru the tip would also dry the paint and cause constant cleaning. Also painting requires a LOT of CFM and small compressors don't do a good job of supporting a spray gun.

Airless spray units are made specifically for this type of spraying but to get a good job the sprayed coating should be backrolled to work the primer/paint into the substrate. I've bought a lot of tools from HF including some HVLP conversion guns but I'd be a little leery of their airless units, I don't believe you can get any kind of quality at that price. You can rent airless pumps that are halfway decent.

With respect to the paint available, exterior paint is exterior paint, interior paint is interior paint. Exterior paint is formulated to be exposed to the elements and endure. Interior paint is not so formulated and will likely fail soon. With painting, the expense is in the labor. No point in applying interior paint outdoors then having to remove it and do it right,

For such a small project, it does not seem wise to buy a sprayer rather than a $10 roller set. Plus, there is a learning curve for a sprayer.

With the disclaimer that "I don't paint", cleaning a paint gun will take as long as it would to roll paint on the exterior, IMO. I don't think it would be more beneficial to use a gun on this application.
