As much as I can understand your disappointment, suggesting to stop buying iPads and go with a S6 lite instead in an forum full of Apple fanboys (or at least Apple lovers...) is looking for troubles...
Having said that, from someone that is not in the Apple ecosystem (but has a lot of Apple devices) and uses both iPads and Android tablets, let me tell you, they are very different beasts. The S6 lite makes sense if you want to draw at the cheapest price possible and watch videos (cheaper than even the 9th gen, better speakers, pen included). My sister bought one for her 14 year old daughter for €280 and she is happy. But she bought an 11in iPad pro with M1 and pencil 2 for herself... While the 2022 version of the S6 lite has a better processor the the older S6 lite (yeah, Samsung is so dumb they didn't even change the name...) it's not even close to the even the A13. Also higher end Samsung tablets had ditched the audio jack too, which is a shame.
I bought the S8 ultra and while it has some great aspects (especially the size) I don't use nearly as much as any of my iPad pros, to the point I almost regret purchasing it (for many reasons I explained elsewhere in these forums, but mainly because, other than for streaming I can hardly find anything where it's better than the iPad pro for someone like me that does not want to replace a Mac or Windows device).
