I have a choice between arming my Moloch pretender with Demon Whip plus Lantern Shield, or with a two-handed Doom Glaive. What is better, considering that he already has good body armor?
whip + shield for sure, if you have gleaming gold shield that would be far superior to lantern, or vine shield if you face undeads / mindless units.
Note demon whip flops vs fire immune or very high armored targets, its good vs mass chaff. Doom glaive shouldn't be used for anything, almost any normal 1 handed weapon with shield is going to be superior to glaive.
