i don't think we'll go through 6th grade ($$$$), but we have our youngest in Montessori pre-K and love it. Since our local school doesn't have full day kindergarten, we'll likely keep him there through that as well.
I completely sympathize with this. I had to kick the ipad off the network an hour ago so I could get the 6 yo to stop playing roblox and go somewhere with me. This was after asking numerous times over the course of 5 minutes and while trying to get results without yelling as often.
Anyone judging and trying to lecture on how doing actions like this is actually counter productive - well, chances are you don't have kids or you yell a lot.
