is the 6 star experience actually that bad?

I just hit 4 stars, (oddly after a match in which i got knocked down and didn't get any kills) as im getting closer to 6 im hearing a lot of talk that essentially getting good at this game is not worth it because the 6 star experience is simply not fun, due to essentially any mistake being punished and the big amount of avtos, mosins and dolches

so people that are actually 6 stars, is the 6 star experience actually this bad?

edit: so essentially i played a total of 1 match in 4 star where i died to a headshot from winfield silenced from 86 meters and im back in 3 stars
