The 2 images are not exactly the same the “official” image is based on Debian (see the Dockerfile) and the Oracle’s image is based on Oracle Linux (see the Dockerfile). Both are based on community package.
I can’t recommend an image or another, it’s personnal preference between Debian or RedHat based distribution. The entrypoints are different. If you see a notable difference between them it can be decisive (didn’t look deeply but official’s entrypoint seems to be more featured).
