Plumbing Preference

I’ve decided to replumb my 12v system. I’ve always used a single drop tube but want to switch over to a setup that will allow me to draw H20, SH, or Roof/PT Mix by turning a few valves. My question, should I use an inline setup with wyes or a cross + 90 setup similar to a proportioner. What do you have or what do you recommend. To me, inline + wyes would be more efficient but I’d like your input if you’ve used one or the other. Please excuse my poor doodling skills

The wyes would be more efficient for flow, the 90s more efficient for space.
