Didn't think SD could get worse. No way they get back the quality that they have lost tonight.
I guess I'm struggling to see what "quality" you're worried about. IMO the only real "quality" pieces Raw picked up are Kevin Owens, Sami Zayn, Ruby Riott, perhaps Baron Corbin (if he's allowed to grow), Bobby Roode, and Drew McIntyre (if they book him like he was in NXT.
That's a lot of addition by subtraction for SmackDown tonight.
Meanwhile, SmackDown kept Daniel Bryan, AJ Styles, Shinsuke Nakamura, New Day, The Usos, Rusev, Charlotte Flair, Becky Lynch, and the IIconics. Plus they're getting The Miz, supposedly getting Seth Rollins, and rumored to get Finn Balor, GoodBros, there's been some rumblings that Braun Strowman is going, and there could be some NXT call ups in Andrade "Cien" Almas, Zelina Vega, and SAnitY.
I'd say based on tonight alone SmackDown is already the clear winner, but I would like to see what they get from Raw first.
