#1 Samoa Joe to SmackDown Live

Overall, I really like the move of Samoa Joe to SmackDown Live. He can reignite an Impact Wrestling feud with AJ Styles, reignite a Ring o0f Honor feud with Daniel Bryan, and create some new feuds as well, potentially with The New Day or Big E specifically.
The problem I have with Joe moving to SmackDown Live right now is the fact that he's just starting what could be a very entertaining feud with Roman Reigns on Monday Night Raw. If Reigns defeats Brock Lesnar for the WWE Universal Championship at the Greatest Royal Rumble, then the build-up for this title match at Backlash includes someone from each brand.
Now that pay per views are going to be co-branded going forward, this could easily be fixed by allowing Joe to appear on Raw and vice versa with Reigns on SmackDown.
