From a storytelling perspective, I think it's likely the weakest of the four Aof series I've seen (and even that says more about the strength of the competition than anything negative about BBS itself), but I just found Ohm and Nanon to be so charming and charismatic in it that I've got a ton of fondness for it anyway. There's a rowdiness and energy to their chemistry together that I thought was delightful.
