As I said, pretty much all skins gives you the options you mentioned. Hell, too much options sometimes. When I modded a NextGen skin, I even added many other fields. BTW, does Decent have "Average Driving Speed"? I find it and "Max Speed" useful. I do not see how it's possible to get more space when you just move those 3 fields from the side to bottom (taking the current street spot) and still have current street shown? It might "look" cleaner to you, but it still take same space.
Font's can be changed from within skin or outside quite easily. It's not hard to even change the skin yourself to "fix" some minor issues you're having trouble with. And you're right about few skins being "sloppy", I won't named them. But they do include nonsense features I feel not "professional." (*sic* animated policemen)
Actually, Decent is not "popular" compared to other skins, check the posts in any forums. I'm not saying it's bad, some people like to eat at McDonald's instead of Burger King's. It's a personal preferences, which I respect. But when you rationalized with some info that's not quite true, it's not right.
I have tried pretty much all versions of iGO/Primo/NextGen ranging from 320x240 to 1024x768 device resolution. And I can tell you that NextGen has the most professional looking native skin.
