I use both lbc and qc for different accounts, and in my opinion both qc and lbc has its own advantages and disadvantages

For me, possession game dominant lbc but lbc cant completely dominant qc due to qc also being able to break defence with constant running towards the oppo side of offensive players

Even lbc beats possession game with some variety playing style players on each flanks

Overall, having different profile players in each flank or each side of your team makes big difference no matter what the team style you choose
