I'm no professional on the advantages of various screw sizes and threads, but I will say this. Whatever you choose to use, standardize it! Nobody needs to deal with figure out what type of screw they used for a specific hole when they have 30 seconds left in a time out before the 3rd match of the Einstein finals (obviously a bit of an extreme scenario, but the same thing applies for the entire build season. And competition season. And postseason and preseason). Choosing one size just simplifies things. You can always buy the same hex driver, wrench, drillbit, screw, nut, washer, tap, etc. and, except for when you have COTs parts with a different screw, you never have to worry about ordering anything else or searching through your supplies to find the right size or having to figure out what is the optimal screw to put in each and every hole. I can't imagine that the structural benefits of having the perfect screw for every joint is worth all of the hassle.
