Bambu Labs PAHT-CF vs eSun ePAHT-CF

I’ve had very good success printing Bambu Labs PAHT-CF on a P1S so far (knock on wood). I am very pleased with the print quality and strength. I stumbled across eSun’s ePAHT-CF and was wondering if anyone has printed both and can comment on how the two compare? I’ve heard rumors BL rebrands eSun anyways? Not sure how if there is any truth to that. Thanks in advance for your time, Chad.
