What is considered the regular and main Lips is the white shirt one, despite the fact that it seems that Lips wore his brown shirt as often or even more than the white shirt.
As for tacky paint, I'm no expert on it, but I'm pretty sure that it is hard to predict tacky paint, as it kinda depends on variables. Personally, I would just go with the Lips that is your personal preference, or, if financial troubles are a concern, the cheapest one.
