Thatch, Nelson, and Gastelum, who's the best WW prospect?

Three guys look like theyre on the peak of being ranked in the top ten, and thats Brandon Thatch, Gunnar Nelson, and Kelvin Gastelum. All three are great at every aspect of the game, young, and have great records. So who do you think has the most potential to become a top tier welterweight. Heres a brief breakdown.

Brandon Thatch: 2-0 in UFC, next fight is soon against Jordan Mein, another guy who could have been on this list. Fought the lowest level of competition of the three(Justin Edwards and Paulo Thiago), but has been completely dominant,

Kelvin Gastelum: 4-0 in the UFC. Fought the toughest competition(Uriah Hall, Rick Story Nico Musoke, Brian Melancon), but has struggled with his wrestling a little bit in wins over Story and Musoke. Also struggled to make weight his last two fights, so his future may be back at 185.

Gunnar Nelson. 3-0 in the UFC, fighting soon against Zak Cummins, who himself is a solid fighter. Fought a solid level of competition(Damarques Johnson, Jorge Santiago, Omari Ahkmedov), and dominated Ahkmedov and Johnson, but struggled a little bit(not a lot, still clearly won) against Santiago.

Id love to see a thatch vs nelson if they both win their next fight, or even thatch vs condit, which would be incredible. IMO in the near future all three of these guys could be contendors
