Your explanation is quite vague. If you want my opinion on includes, it's reliable, you can load it inside any gamemode. I'm not sure how fast it would be, but I imagine tad slower due to the fact it looks for the files within your folder structure. I might be wrong however. And when you don't want a certain script, for example a filterscript, you simply unload it, where in comparison to a gamemode, you'd have to remove it from the GM, accounting fixing errors if any occur.
