Well let me see.
For A and B it would be Fairy Tale. Though as people have mentioned ALL of the "Most powerful wizards" are male. Though I only seen 60 episodes it is freekishly not falling into the gender tropes I hate (for example: Females are much MUCH more likely to fall out of competency or give up fighting then male characters... or even relevance). Though given that "Anime hates women" I am sure the two main female protagonists will be made incompetent and irrelevant eventually.
The WORST for B and A that is from a modern series on the male side is probably "Yakkate Japan!" and don't get me wrong it isn't a sexist anime, I feel like its gender imbalance has more to do with the writers preferences and a change in the dirrection of the series (with it starting to cater overwhelmingly to the male lead). As the female lead is actually not only thrown aside and her plot forgotten but the series, it is a comedy afterall, likes to poke fun at the fact that she is so irrelevant even though she is the closest person to a true main character at least in terms of backstory. As well of the four female characters who can bake (this is a baking anime/manga) one never enters a contest and is thus useless, two of them are incompetent, and the last is psychotic and kinda entertaining sometimes.
-Oddly enough one character I thought was female given he had purple hair and has a female voice... He is a guy!
Though getting terrible animes for A and B at the same time isn't particularly hard, even for series with a wide cast and plenty of females to chose from.
" Although at first it really just sits in the stereotype of 'guys protect defenseless girl' but gets a little better later on."
Yeah but given it is Sakura from Cardcaptor Sakura who in her series ended up needing to save his butt like crazy. I can understand that.
I am never really bothered with characters who are incompetent (from the series main source of action... So in this case it is fighting, something Sakura cannot do) not being able to do much. I am REALLY frustrated at series with competent females or females who should become competent due to their aspirations... who don't because "They are women and we need to have the main character have all the glory".
Heck Kenshin an anime I like was worse because the female lead was supposively "really strong" and with a "Supreme warrior spirit" who only has ONE successful fight in the series and she trains constantly in the series (more so then even the male lead). At a certain point I started to joke that she was the weakest character in the show and say things like "No don't attack that knife weilding maniac he will beat you!" and yeah she would lose. Less skilled and weaker characters actually have a better track record then she does. It was frustrating because as a character I actually really liked her and as someone watching a story to see a character set up to be a competent warrior for the new age be so terrible at what she does is weak.
Heck I didn't even like it when "How to Train your Dragon" did it and it was a pretty decent movie and not an anime at all. Astrid who is a competent female character with strong aspirations that are constantly shot down by our male lead... just completely throws it away and doesn't even get to really resolve her story because "Her competence would get in the way of our hero being heroic". -_-
Holy cow I went on a tangent and actually lost complete track of time.
Honestly you should remember that B only matters if it remains that way. A lot of series start off promising enough with strong and important female leads and side characters only to smack them with irrelevence in the final act.
