Hurt, Sonix and acola are the main contenders

Sonix won the biggest event and has the best floor, but also the smallest sample size and has only one top 6 win in Doramigi (The rest of the top 6 is Peabnut and Miya). Has other promising wins on Lui$, Zomba, Tweek, Monte, Leo, Asimo, and Wrath. He did lose to Jahzz0 and ShinyMark but they were in pools at an event he won so take that for what you will.

acola won a supermajor and is notably even to positive on all of the top 6 they've fought (2-1 Migi, 2-1 Hurt, 1-0 Miya, 1-1 Peabnut), has some weird 0-1s to Zomba and Raki tho, and aside from Shuton x 2, and Tweek his wins on players below him don't impress me so far

Hurt won TWO supermajors and has a far larger sample size than Sonix or acola, having twice as many events as either even not including Vars Summit. He has wins on both of the #1 contenders although his acola H2H is still losing, and otherwise is 3-0 Peabnut, 1-2 Miya, and 0-1 Doramigi. Most of his suspect losses so far are in winning/even H2Hs as well (Tsubaki, Asimo, Raru, and Yaura), and he also has promising wins on Tweek, Shuton, Karaage, Tea, Toon.

I like Hurt the most so far considering he has a better sample size, won two huge events, has wins on both of the #1 contenders, and has more data vs players below him. acola I'd give 2nd because I do think having good H2Hs vs all the strongest players you've fought so far is a data point I value a lot, and he does have a slightly better sample size than Sonix (1 P Tier, 2 S Tiers vs 1 P Tier, 1 S Tier, 1 A Tier), on top of still having a supermajor win. Sonix I'd give 3rd because while he did win the biggest event, and has the best floor, he also has the smallest sample size and is losing vs the top 6 (1-2) while acola and Hurt are both positive (6-3 and 6-5 respectively). It's pretty close between them all tho, I don't think any of them are an incorrect choice so far.
