1. Well he sort of defeated a calamity, Chopper neutralised the virus, Zoro destroyed the weapon and the vast majority of his power came from a literal power up in a can which he absorbed, basically a handout from Judge. Realistically Judge did more work in that fight than Lanji, it wasn't like he beat him through amazing technique and haki.
Zoro fandom were right here, since before his genetic upgrade courtesy of Judge and the raid suit there was absolutely no way for Lanji to defeat queen. How were they to know Oda would allow him to absorb raid suit abilities and 'awaken'? Not an L at all.
2. A bill bounty fine, but he's also only the 4th highest bounty on the crew. I have no idea how you're trying to turn this major L into a W for Lanji that's just desperate. He is now 4th strongest behind Jinbei until proven otherwise.
3. IIRC sanji got bitch slapped by drake like fodder in Wano, granted he managed to defeat queen (sort of) so you can make an argument for him but he still hasn't really been given the same level of importance. In comparison Zoro took on Hawkins, Apoo and Killer and came out winning or looking superior in every exchange. So yeah, Lanji may have entered the worst gen conversation now (fandom only), but there are only 4 or 5 relevant supernovas left, he's started a race 10 years behind that has all but finished. Better hope he's faster than he was against Saturn.
4. Recognition? He did all of jack shit in WCI, he got busted up by Judge, Yuen and Daifuku all in the same arc and he says himself it only went up because of his daddies name
