At least for this device, OpenWRT/LEDE is actually more robust for the R7800 than DD-WRT, considering LEDE has Cake QoS which performs extremely well which isn’t even available on DD-WRT. I believe they also use an older kernel than LEDE. It doesn’t mean I can generalize and say LEDE is necessarily better than the DD-WRT as these guys put a lot of work into these devices, better to say they have different approaches and performance depends on device in consideration. In regards to Broadcom devices for example DD-WRT actually does better as they have an agreement I believe with Broadcom for drivers while LEDE doesn’t even support WiFi on the 4366 based units.
Having said that, stock derived firmwares in many cases usually perform better due to hardware NAT acceleration and also WiFi due to proprietary drivers. Things like improved CPU optimizations, newer packages, some extra features etc seen in open source can sometimes also added into stock derived firmwares by devs like RMerlin and Voxel. In addition newer models seem less and less open source friendly so this approach seems like the best of both worlds.
Thank you for the clarification.
Now I'm thinking about the installation of LEDE, but a little scared because it allegedly after it is difficult to restore the native firmware.
