Are husband lovers loyal to a select few husbandos or are open to a large harem?
I remember there being a post about genshin husbandos and the reason for them being made less and I remember that it was translated from Chinese to english.
So what I understood from that post was that the spending behavior between the waifu collectors and husbandos collectors is different. In simple terms a waifu collectors is willing to spend for any new waifu as long as they appeal to the male gaze however husbandos collectors usually stay loyal to that one husbando and invest as much as possible on that single husbando from in game cosmetics to merch to fanart and so on.
Of course this behavior is not a monolith of husbando collectors however it seems to be a majority in CN. In fact many fangirls often have this rivalry with other fangirls and are full on defence Force for their husbands.
This can also be observed in the LADS community where there are sometimes hostility between the fangirls. Take this with a grain of salt because I am speaking from what I remember from that post which only covered Hoyo's perspective.
In short waifu collectors are more so invested into harems whereas Husbando collectors are loyal as hell to that select few.
