I will say the Taskbar on OneUI is wonderful. I'd like Apple to steal that feature if/when they make their own foldable. I feel like I could use both OS with minimal issues.
Yeah, I enjoy using the taskbar.. its what sets it apart from the Pixel Fold. It would be dope to see that feature in a Apple foldable, Samsung took the 3 dot contextual menu found on iPadOS (Enter Full Screen, Add Another Window, Minimize & Close) and they use it for SplitScreen, Pop-Up Window & Close.
In terms of multitasking, Samsung is above the crowd... one of the reason why I prefer it over other smartphones.
I will give Apple the nod however regarding iMessage and customer service in their stores.
I've been getting by with BlueBubbles... I like the themes it provides (two column layout on the inner screen), plus I get all the reactions, type indicators and read receipts that iMessage is known for.
I've dealt with Samsung's customer service in the past... I've had good experiences, all ended with issues resolved successfully. But I can understand when looking through various forums and reading users horror stories.. that can cause some concerns.
