I resisted mods for several years, but finally started using MCCC after the patch that eliminated some of the original cheats, 'cuz I needed to restore some broken relationship bits, if possible. So I hear you!
I've never had MCCC break anything. I pull the Mod folder out of the TS4 folder (move it up one level to the EA folder) before I get the latest patch, & of course I wait until the mod's updated or verified as compatible (I get that info 1st from SimsVIP & then from the MCCC website). Once I've verified or updated, I move the (updated) mods back into the TS4-level folder.
It's less work than updating NRAAS, as there are fewer modules.
Hope this info is helpful!
