Best Cheap 3D Printer Filament?

Hello all,

I'm working with about a 20-25$ budget, so please keep that in mind. I'm going to get it with a new Ender 3 because it doesn't come with filament. I don't really care about the color too much because I might spray paint it, but I would prefer grey or white. I know that there is Hatchbox, but the reviews aren't the best, and same with the Amazon Basics filament. Thanks!
