I work on Positron and I'll chime in! If you only use Python (not any other languages) and you are happy with Spyder, then Positron might not be compelling as something for you to switch to. If you ever find yourself using additional programming languages for your work or you want a more customizable, extensible IDE, then you might consider taking a look at it; I don't expect it would be an onerous switch coming from Spyder.
