BL Touch & Config.h

Can any one straighten me out on which lines to comment out and which lines to UN comment, for the two different BL Touch hookups? I know there are different lines to activate or de-activate depending on whether you run all five wires to the “Z_PROBE” port, or the three ‘servo’ wires to the “Z_PROBE” port and the black & white wires to the 2-pin Z_STOP socket. I don’t know if one of those has an advantage over the other (simpler?) or if that’s done to address a specific issue… and I keep getting conflicting information about the config.h settings for each. I’d appreciate any clarity you could come up with!

edit: I’m running a BTT SKR Mini E3 -v- 2.0 in an Ender 3, if that makes any difference.
