I definitely feel like a lot of people underestimate Suletta's skills as a pilot because she's a woman, she often fought in duels instead of a war and she was helped by Eri early on (though only with GUND-Bit control, which isn't significantly different from how non-Newtype bit control systems work in other AUs, but somehow that's usually only a knock against Suletta, I wonder why).

Just remember that when she took on Quiet Zero in the Calibarn by herself, she was not only fighting the Aerial Rebuild and it's 11 bits, but also it's support system of possibly over a hundred Gundnodes, some of which were equiped with 4 bits of their own. All while suffering significant physical strain from the data storm. She survived that battle while only taking a couple glancing blows from Aerial, destroying multiple Gundnodes in the process, all while only trying to disable Aerial.

Also remember that she started training in the Aerial when she was just a child, and despite not fighting in wars, had years of experience piloting mobile suits in harsh, dangerous conditions by the time the series started. She was already a better pilot than basically all her peers at Asticassia when she got there. She defeated Guel even when he had cheating in his favor. She practically wiped out the entire Grassley team all while specifically not using Eri to handle the bits. She defeated the Gundams she did face, even the one piloted by a child soldier trying to kill her. Her struggles in season 1 had more to do with her own self-esteem and self-confidence issues than her skill as a pilot.

(And before anyone claims that she only looks so good becase she had a technological advantage over her opponents, I think that's a laughable thing to hold against her because basically EVERY Gundam pilot holds a technological advantage against their opponents if they're not Gundams or aces in highly specialized customs, with some rare exceptions like Amuro in the Gundam at the end of the OYW. Again, just like with Eri controlling the bits, this is something fairly common among Gundam pilots but is one thing I see that is often specifically held against Suletta for some reason.)

Is she one of the best Gundam pilots ever? Probably not. Is she only average or bad? Fuck no. Her evasion skills alone are some of the best in the franchise, especially for not being a Newtype, Coordinator or Innovator. And she displayed those skills all while suffering from severe physical pain that almost killed her and left her disabled afterwards. There's only a small handful of Gundam pilots who performed that well while their Gundam was actively killing them.

She’d absolutely prove a challenge to pin down and defeat for even the beam spammiest of pilots, and if she fought seriously after fusing with Eri/Aerial and exceeding score 8, I think she’d be an absolute menace to anything short of some of the more ridiculous mobile suits out there.

I just don't see how you can objectively watch her performance at Quiet Zero and come away thinking she's only average or bad unless you're biased against her because you hate the show or you're just plain sexist.
