How can you say you're not picky, and claim the roller finish is just as good as spraying at the same time? That just confuses the daylights out of someone that might really be looking for a real answer in the future 
Goodness me. What a pedant.
The finishes on spray and roll both look "good enough" to me. Sure, they are different. Spray when done correctly gives a flat mirror finish. Roll will always give a textured finish.
Is one "better than" the other? I don't think so. They are different, and at the end of the day it boils down to personal preference. I like the slight texture the finish has on my cab. It also helps mask fingerprints a little better than a pure mirror finish that would require constant cleaning to wipe away grubby children's fingerprints. But that's not to say that the finish is superior in any way to spray. Again, they're different. Apples and oranges.
So, when it comes to spray vs roll, I'm not picky. They're both different, but from a "pretty" or "ugly" point of view, I find both to be "pretty".
If I was a pedantic sod and want a super-shiny finish akin to a showroom car, then sure I'd have an issue with the above. Me, I care more about the games than the finish of the cab. Hence the phrase "I'm not picky".
Is that clear enough for you? Or do I suffer yet another round of criticism for not being anal enough about the finish of a homemade MAME cab sitting in a dark gamesroom underneath my house where no-one but my kids and I venture?
