As an Android user, I always like the old school AOSP. There's a lot Google has done a nice job with over the course of Android. Still, because of the Apple like approach, there's more work to be done for a much customer like me to set the device up how I want. Google over the years has just by fled stuff I to their ROM I don't like, never used and would have preferred the option to fully uninstall vs merely disabling.
It was this as why I liked to root back in the day. I remember those Gapp less ROMs. Or how some of the Gapps packages were so slim you could get away with it (loved those Slim ROMs).
This is partly why I like some of the Chinese OEMs' ROMs. There is some useful stuff in the software that Huawei, Xioami, etc offer - especially if one wants to wean off Google services. As aways, their stuff too is fraught with stuff that's a pain in the *** as well. Even they are falling more under the Google push, if you see the differences between the Xioami Global vs Chinese ROMs for example...it's getting harder to drop some of the backed in Gapps I don't like in the Global ROM.
I'm not going sit here and state that LG's skin is better. What people use are a matter of preference. I will say the closest thing to what I've liked in a long time was the Essential ROM. It was in the vein of those slim ROMs. I'm merely in the minority here, so most won't care. Still, Google's version of Android and iOS these days are really starting to look and feel like each other - which is good for most people and not so much for outliers like me.
