No but this has been asked a hundred times and the answer has always been that Iz*One and post-Iz*One had the most benefits and advantages compared to all the other seasons of Produce groups.
People always forget that for the first season, there was no "Produce hype" or "Produce privilege" or whatever you want to call it. It was the first of its kind and what got them attention was the large scale 101 contestants and their performances that went viral like Bang Bang etc. The trainees were all mostly from no-name companies or small companies with idols who were desperate to debut and saw it as a last chance for a debut. It wasn't like the second or third season where people knew it was a red carpet to success, and had all the built in hype.
And as a lot of people have already said, IOI's contract lasted for 8 months, and barely had time to build a fanbase. Wanna One was 1.5 years, and X1 didn't even get a chance. Iz*One had the longest time, had the built in fanbase from Japanese 48 groups with Sakura, Nako and Hitomi.
Everyone knows about all the shit contracts and what not, but no one talks about all the companies differences. Post-IOI companies had Jellyfish and Fantagio, both are acting companies with little to no idol group experiences (VIXX and Astro are the only groups), MBK was always shit, Pledis had After School and Seventeen, so they were promising but unexpectedly disbanded PRISTIN less than 2 years into the group. If it wasn't for Produce and IOI, they would have been one of those groups that no one ever know or hear about and quietly disbanded. Compare this to Iz*One where the groups are from HYBE, a BIG 4 company at this point in time and Starship who's previously managed Sistar and WJSN, both groups with hits esp Sistar and have always been stable in the mid-upper tier of girl groups.
And yes, I agree that people are kinda overhyping Iz*One success. IVE is doing fantastic, Lesserafim is up there too just because they're from HYBE, Yena had Smiley which did well, and she's always around in variety, but Smartphone did not find the same success.
The others are all a few tiers below that. They get good sales from their fanbases, but Yuri, Eunbi and Chaeyeon have essentially no presence in the charts, neither are they popular or well-known enough to be appearing on TV shows or having CFs. Hyewon is not even the main lead in her web-dramas and she's doing some YouTube thing, but are we really acting like that's doing great now? Minju is acting as a supporting cast at this point in time, and Nako and Hitomi are in Japan, so I won't comment too much on that.
People are calling all other Produce idols as flops, but they're doing just as well, if not even better. Somi, Sejeong, Chungha, and Daniel are all A-tiers. Jung Chaeyeon has no problem getting lead roles on TV dramas, Park Jihoon's drama just went viral and he seems to be the next big acting idol. Ong Seongwoo is booked for like 5 dramas and films, Kang Mina is consistently getting work in TV dramas. Jieqiong and Guanlin are both booking lead roles and variety shows in China as well. If anything, getting work outside of music and into other a more respected field of acting is a much greater success than the idol life
