The highest level of performance was probably McDavid in 2021, but I'm hesitant to vote for it because it was an unusual season (only 56 games, and only against divisional opponents). Obviously none of that is McDavid's fault, but I can't ignore the context either. The fact that he came close to matching that level of performance in 2023 definitely helps (it proves it wasn't a byproduct of that unusual year).
But I'm not certain if McDavid in 2023 was better than Jagr in 1999. Jagr scored 127 points in a much lower-scoring season. A crude, high level adjustment based solely on leaguewide GPG gets him up to 154 points (essentially matching McDavid's output in 2023). Jagr pretty clearly had a weaker supporting cast (not that McDavid had strong support, but it's hard to overlook that he collaborated with Draisaitl 75 times - Jagr's best teammate was Martin Straka). On the other hand, McDavid was 35% ahead of the next closest non-teammate - there were five different players who were within 35% of Jagr. I haven't voted yet, and am open to hearing arguments, but these were the seasons that immediately jumped out.

2022-23: ESG: 2.39, PPG: 0.65, SHG: 0.10
1998-99: ESG: 1.84, PPG: 0.69, SHG: 0.10
22-23 McDavid:
82 GP: 64 G, 89 A, 153 P (1.87)
98-99 Jagr in 22-23 levels:
81 GP: 53 G, 96 A, 149 P (1.84)
McDavid 2023 dominated his peers to a greater extent and also has better numbers when the special teams and even strength are adjusted accordingly. Is also the first season since Gretzky 86-87 to lead outright in goals, assists and points. As someone who is a huge Jagr fan I think it’s pretty easily McDavid even though this was his premiere season that I enjoyed firsthand and up close.
2020-21: EVG: 2.25, PPG: 0.57, SHG: 0.07
20-21 McDavid in 22-23 levels:
56 GP: 36 G, 79 A, 115 P (2.05)
This season however beats them all. Easily the best season for non big 4 on a per game basis. The only seasons that I’d say that are better (for Gretzky and Lemieux only) are 82-87 Gretzky, 89 and 93 Lemieux. That’s it really.
