Considering I'm taking alot of these takes from today's fans the well will dry up quick so if you got a few Hot Takes of your own, I shall give you my two cents.
"Misty's still the best Pokemon girl"
That's a funny way of spelling Dawn. Dawn is the only female character in Pokemon history to have equal billing with Ash and the only former female companion to actually turn up in person to his Championship match, Misty was memorable but has very limited appeal.
"Gundam Wing is the best Gundam"
Even Heero thinks your statement is a load of bull.
Real talk, there is no definitive best Gundam series as each series brings something to the table that it's contemporaries don't have, looking at the latest series Witch from Mercury has Utena vibes for instance, anyone who does name a best Gundam series is likely to have only seen that Gundam series, another issue the franchise has, is that it's very difficult to like more than one Gundam series because of how wildly different the content can be each series.
"Goku is not a good character"
I've seen this alot, in fact it's the most common hot take next to the argument on fan service and subs vs dubs, don't think we'll be seeing the last of it anytime soon. Goku's status is usually helped by the fact that funimation made him act more heroic but he's still raised in the boonies and taught martial arts by a known pervert and it's pretty obvious when Toriyama has more input as his sense of humour is utterly juvenile, I can see where the argument is coming from, at the same time like the grandmother that voices him in Japan, it's a familiar face that reassures you that the world is okay, not every hero is written to be perfect but can still be a symbol of peace.
"Modern Isekai is the worst anime genre ever created"
It's not, you're just sick of the over saturation of the genre in recent years, the actual worst genre is surreal comedy, if you don't believe me, watch the Super Milk Chan Show and you'll be begging Truck-Kun to send you to another world.
"Sailor Moon has aged like milk, and there's nothing it did well that Nanoha and Precure haven't done significantly better since"
Precure's existence relies on homaging previous ideas from older magical girl shows, even the original referenced the Dirty Pair; Precure even had the director of the Sailor Moon anime direct Hugtto Precure.
Nanoha is just a trashy magical girl show that's trying way too hard.
While the content of the 90s Sailor Moon anime is a little dated, it still has a charm that keeps people invested, most anime fans when asked to name a magical girl show, the same three shows will turn up, Sailor Moon, Madoka Magica and Card Captor Sakura, it has the strongest staying power in all of anime along with Evangelion and the Dragonball franchise.
