One of the things I really disagree with is that benders in LoK are weaker than in ATLA.
Like, maybe normal benders kinda were. Peaceful times and all, average benders in LoK probably weren't as strong or trained as people who were forced to learn how to fight because there was a war going on.
Now, top benders, benders who actually take a role in the story? Not really.
We didn't actually see many Firebenders in LoK aside Mako, Iroh II, P'li and 88yo Zuko who we only saw fight once at the North Pole at night, at his weakest, okay. And well, Korra. Still, P'li was one of the rarest benders in the franchise. And Mako was a pretty talented Firebender, and Korra was about his level except the lightning generation thing. They're not Ozai or Iroh, okay, I'll give you that, but about Show Zuko level. And Iroh II was pretty good too.
We didn't see many Airbenders in ATLA, with the whole Aang being the last one thing. We know Gyatso was great we didn't actually see him bend (aside throwing pies or messing with Aang to cheer him up), nor any other airbenders aside other kids-- and also, all that was before ATLA, in flashbacks. Aang was a prodigy and very powerful. But in LoK, Tenzin wasn't a slouch either. Neither was Jinora, who was also a spiritual prodigy, or Zaheer, or even Kai, who was also pretty good considering the kid had only gotten airbending a few weeks ago. And Korra herself ended up becoming a pretty good airbender. Neither her or nearly all of the others were at Aang the Airbending Prodigy's level, okay, but all of them were good, most of all Tenzin. Tenzin was one of the strongest benders in the franchise overall, and tbh he was probably better than ATLA Aang (but probably not as good as Peak Aang).
The strongest Earthbenders in ATLA are Toph and King Bumi, and most of all Toph, I agree with saying that they are stronger than all the other Earthenders in LOK; the only ones who could keep up with them in terms of just earthbending are people like Yun or Jianzhu from Kuruk's and Kyoshi's Era, or, you know, Kyoshi herself as an adult. However, those are the two only Earthbenders who stick out more than LOK'S. The other talented Earthbenders in ATLA-- guys, come at me. Come at me, look me in the eye and tell me that you actually think Tyro or Haru could beat Lin, Su or Kuvira. Tell me that you actually think that any Dai Li agent of Aang's time could beat Bolin or Ghazan. C'mon, tell me, tell me that you actually believe that. Toph was the exception of ATLA, not the rule. Aside her and probably Bumi —and Lavabending and Metalbending could still give any of the others an advantage against him that gives them the ability to put up a good fight—, any Earthbender in LOK could probably beat any other Earthbender in ATLA without breaking a sweat.
And in terms of Waterbending it's not just that the Waterbenders in LOK are as strong as the ATLA ones, it's that most of them are stronger. The only notable Waterbenders in ATLA (the only ones if we're being honest, we didn't see many Waterbenders). Were Katara, Pakku, Hama and Aang. Aang was a weaker Waterbender than any of the previously mentioned ones, and Bloodbending inventor Hama got beat up by 14yo Katara. So, really, the strongest ones are Katara and Pakku. Now, Legend of Korra had, let's see *checks* Amon, Yakone, Unalaq, Tarrlok, Korra herself, Ming-Hua-- damn, even 'weaker' Waterbenders like Tonraq, Kya II, Eska or Desna are still pretty skilled. Most Waterbenders in LOK are insanely OP, and generally stronger than even the strongest at ATLA. For example, in terms of raw power —idk about skill, that's a different thing—, Amon beats people like Katara and Pakku easily; his raw power was, well, more powerful than Korra's, who has the biggest pure Waterbending feat in the franchise, and than Tarrlok's, who had more raw power than Korra, at least in Book 1. The guy was likely the most powerful non-Avatar bender in the franchise.
