Mtm and Zonal is a big debate, I played both and won with both. What i can say is:
- Mtm marking if used properly can really be game breaking , but need too much work for the manager as you need to adapt always your formation depending on oppo or else you will get a big lose.
-Zonal marking is the best beacause your team will defend as a "collective" relying more on the offside trap to compensate possible formation flaws ( like a player not marked , pacy players that cannot be man marked. ect... ), you can play any formation with this.
Regarding what The Savage says there is no sure advantage if you use low press/zonal vs hard press , you can stay deep -low press and defend but that doesn't mean you will win , if oppo manage to close you on your half and didn't let you build up from the back you are going to lose. All depends on tactics.
