while I appreciate everyone naming their favorite companies, this is the only real answer to the question. It doesn’t matter at all which registrar you use, it’s about brand recognition, support, add-on services, and cost.

[source: friend founded his own (now defunct) registrar and I would help out. Even when a registrar goes out of business there’s no real risk, as there are plans in place to hand off customers to other sites]

You make a good point, but OP’s pick is still a really good choice. In early 2020 my old desktop became the new home server: i7-6700K w/ 32gb ram. It’s been going strong every day since. Unraid with Jellyfin, pihole, HAOS, and like 20 other containers running. I generally serve untranscoded 4k hevc videos locally, but I tossed in an old geforce 900 series for both on the fly transcoding as needed (honestly, it’s rare if ever) and for tdarr.
