A bunch of GUIs, or a load of PPVs?

The mod I'm working on needs a lot of complex GUIs and I have thought of two solutions. 

1. A whole tone of seperate GUI textures that you jump between with buttons and tiny scripts.
2. A smaller number of GUIs with a bunch of images set to be visible when certain PPVs are true and a bunch of Scripts on buttons to switch those variables.

Is there a better solution? If not which of these two would work better? I am new to modding, and while I haven't had much trouble getting things to work, I know very little about what things impact performance.

Any advice would be appreciated! Thanks!
