Elaborate please.
There is no direct difference between them.
Traditional eSIMs are just eUICC chips soldered to the logic board or virtualized in some trusted environment eg. TrustZone.
A physical eSIM is just one of those eUICC chips in traditional SIM card form factor.
Here is a common chip that can serve as an eUICC https://www.st.com/en/secure-mcus/st33g1m2.html
You could argue there is benefit to the lack of removability and the ability to automatically wipe the eSIM on device wipe, but otherwise there is no difference.
