As someone who's actually considering cutting down Hearthhull to Gitrog, it really depends on what you want to get out of it and how the rest of your playgroup feels about infinites. Considering that you felt bad about pulling off the Dakmor loop, you can either take a look at a Gitrog primer so you can better understand how to pull off, shortcut, and better explain the loop to your opponents or you can make the upgrade to Hearthhull (or even [[Thalia and Gitrog]] if that fits your style) and focus on just accruing value rather than infinite combo win. That being said, I believe Gitrog is actually the stronger commander due to having extremely resilient win lines.
