> This costs more than twice as much as GitHub, does it provide twice the value?

This is not always the right question to ask. One can argue that both products are too cheap with respect to the value they offer, so the relative value between the two is irrelevant.

In other words, if you can afford $X and $2X without even thinking, and if you think even $10X would be a fair value for either, it doesn't matter if the $2X product offers only 20% more value. You would simply want to get the best, even if it's a diminishing return. I believe $9/month/developer can be classified in this category if you are actually doing code reviews.
