Getting the extra gold from X is great but I still want be maximizing my runs and chances at plat armors. So i use the extra charisma saved up to do 4 X runs at reset then run H with all my natural regeneration, because as you said it breaks even. The amount of additional X runs you can get over H changes depending on your prince level, which determines how much of each resource you can have saved up. Also be aware when maintenance is happening to get runs in beforehand on Monday.
