It 's like economics: there is no good or bad system. There are tactics adapted to the situation or not. I honestly hate 4-4-2. I cannot remember a loss against this. I can suggest basic formations I hate to play against like 4-2MC-3W-1 or 3-6-1 butterfly for which I couldn't come up with convincing counter. But indeed 4-5-1V can be a pain in the a... as it's my formation. On top of that, you can easily counter the known counters for this. Which makes it a killer !
