First of all, both are good and I am not against hotio's template, I find it nice to have support from bigger sources. I personally use my own image, because it uses the developpers docker container and I spoke the developper and added him to the template's github. So when there's an update you get it as soon as it's available, also if a new release as a breaking change you simply remove the template and it's gonna be fixed because the dev will have updated it on my github. The main advantages of hotio's is that it supports arm and has GUID PGID support added in the docker image, also as he stated he verifies everything works fine. In the end, if you want the latest stable release go with my template since it's developper backed. If you want a more stable version of it use hotio's. I personally didn't have any problems with mine, also keep in mind it's not going to be perfectly stable no matter which template you chose because it's still ALPHA software 🙂
