Well, everyone has an opinion, I guess. I have used the RX10 iii and then iv as my general travel camera for six years now and I think it's a very good bridge camera. If you can accept its limitations, which include limited high ISO performance and slow response (e.g., focusing) compared to a DSLR or mirrorless camera, you can get some terrific photos with it. It's also relatively delicate, i.e., you do NOT want to subject it to rough usage. A short drop in Africa in 2019 ended the useful life of my RX10iii, which I then replaced with the RX10iv.
I will add that the RX10iv is now a bit long of tooth (released in fall 2017) and Sony appears to have no plans for a version V. It appears that the era of the top-tier bridge camera mighy be coming to an end.
