player perfomance

[Diegito]

hi all.i have a team ( Diegito FC) lvl 5
i want to make a question about player perfomance,as it "seems" after game ends.
what is better for my team?
if a "top" 5* player gets a "6" for his perfomance for a game
or a lower quality 1* player gets a "9"?
an exmple,to make understand easily what i am asking:
lets suposed that my team played a match. i used 2 DC`s:
one DC quality 39(5* for me) ,game ends,stats,perfomance 6
the other DC quality 16 ( 1* for me),game ends,stats,perfomance 9
that means that in that unique game the 1* DC was better than the 5* DC or not?
cause if yes,then i see no point have players with many stars,high quality but bad perfomance.
no point buy tokens and buy better players...
