Which should you buy?
The HDR-AS300 is the clear pick on raw spec strength, leading by 23.6 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the HDR-AS300 if you care most about waterproof depth and max 4k fps. The biggest gaps in its favor are waterproof depth, max 4k fps, max video.
The RX0 II similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
