Well-deserved players to be in the finals! Both of them have put in a ton of effort for the tier, so it's awesome to see the ones being rewarded for it.
As for quick predict, I'll have to go Sleid imo. Sleid's the slightly better player, while I think Pandadoux is a clear better builder, but Pandadoux hasn't put much time into building/meta developing, and I believe Sleid will find openings to create a snowball effect to his victory. Both are traditionally senseful in their building, and distinguish themselves from very wacky things by having some foundations in the tier, so expect a clean game 3 where who gets the right knock-offs and breaks in like 20-30 turns. I doubt both of them will choke or throw the endgame unless they get unlucky, so who wins the mid-game scenarios wins the game most likely.
