What’s the best way to plan your resources when you’ve got several projects and several people?

I’ve made this interlinked spreadsheet to I can play around with the methods
it seems to me that each way has pros and cons, so you could choose the best one, OR, use all three interlined and have one as the data input view and then check the other two to see if it works out as a good plan, and change the input until you’re happy.
In which case, which one should be the data input view…?
Hmm
This is my idea of fun. Do I need professional psychiatric help?
