Well I didn't find any issue in this build that's why I didn't switched or tried to switch to sairam build (and nicheream sir's build was also based on 4.9 kernel it didn't had any problem same for the build I suggested to you. In simple words this is the best alternative to nicheream sir's build)
I had flashed Fork LOS 17.1 by Sairam last week and I am happy to report that idle drain is nowhere as bad as some had reported in earlier builds. Occasionally overnight drain is as low as 0.25%/h but mostly in the 0.6-0.7%/h. Keeping Battery Saver on seems to help quite a bit in this regard. I haven't flashed any GApps/microG yet though which could possibly worsen idle drain.
System responsiveness is much improved. I hadn't used Nich's LOS build so I can't compare to that but its really fluid. Active drain while browsing is a bit inconsistent but on average ~10%/h.
I still have to check Gabrielse's 4.9 build and LOS 16 Official.
