Very interesting! Really appreciate this insightful feedback!
So in general, Rob Braxman and GrapheneOS have a huge debate/dispute. In general, the privacy and security community seemed to have sided with Graphene, against Braxman. The objective complaints I've seen are that he sold many phones with the same IMEI device IDs, which caused some customers to have issues with service.
Unrelated to phones, I personally dislike his use of Big Tech. For example, He used Amazon to host his "private social media". Indiegogo uses google and such. While this is not directly related to the phone, it makes me question his ability to remove all Big Tech telemetry with his apps, when he could not do so for his own website WhattheZuck.net or brax.me (check them out with uBlock Origin)
Regarding Ubuntu Touch, please see this article from Madaidans on the downsides of Linux Phones for security:

Regarding his new operating system advertised here, it's an Android skin without Graphene’s advanced security features.
Regarding his hardware, as far as I know, it's from the same company that does the SimplePhone, which is not that competitive hardware specs wise.
In summary,
The only plus side is that the hardware is not manufactured by Google, but much weaker security at the OS level.
Discussion
