My main complaint with OVH is that their checkout process is broken in various ways (missing translations so you get French bits, broken translations so placeholders like ACCEPT_BUTTON leak through, legally binding terms with typos and weird formatting because someone copied them from a PDF into a textarea, UIs from the 90s plastered in between modern ones, missing option to renew a domain for longer than a year, confusing automatic renewal setup, and so on). The control panel in general is quite confusing. They also don't allow hosting an email server (port 25 blocked), iirc the docs tell you to go away and use a competitor

I didn't have any of these web UI issues with Hetzner, but iirc OVH is cheaper for domain names, as well as having very reliable and fast DNS servers (measured various query types across some 6 months), and that's why I initially chose them — until my home ISP gave me a burned IP address and I needed an externally hosted server for originating email data (despite it coming from an old and trusted domain that permitlists the IP address) so now I'm with both OVH and Hetzner... Anyway, another thing I like in OVH is that you can edit the raw zone file data and that they support some of the more exotic record types. I don't know how Hetzner compares on domain hosting though
