Photos taken with Asus Zenfone 5 (2018) ZE620KL
Here are some pictures taken with Asus Zenfone 5, some images are taken with manual setting(Pro) but most of them are taken in auto mode.
I had Samsung Galaxy s9 before Asus and i would have to say that there's not a big difference in image quality.
Biggest thing for is that Samsung focuses even if camera is very close to the object, with Asus you cant get to close to object since it wont focus then but difference in distance is minimal.
Personally definitely prefer Asus Zenfone 5 because it has many features on image settings and modes what Samsung Galaxy s9 doesn't have.
There;s probably even better phones with better cameras there but i can only talk about these two phones.
