The Win 94 is a superior design. The Marlin is neither stronger nor simpler.
The 94, like the Win 92, uses compound leverage, where the Marlin uses a fixed fulcrum.
Superior bolting. The locking block has more surface area where it contacts the bolt than the Marlin does. It also completely blocks the path of the bolt. The Marlin uses a LARGE square notch cut out of the bottom of their bolt that is over 50% of the vertical thickness of the bolt. Marlin's bolt is a round peg in a round hole; while easier to make, I'll take the rails of the 94 thank you.
Better carrier design...large surface area contact between lever and carrier, compared to line contact with Marlin. Carrier rises at END of forward lever travel, Marlin carrier rises at BEGINNING of return lever travel.
The combination of simple leverage at beginning of extraction and carrier rise timing leads to a non-smooth, bumpy feel with the Marlins.
Rattling, looseness...these are manufacturing issues, not design issues.
Ease of takedown, while convenient for the user, doesn't a better action make.
Scope use...for those of us who don't scope our levers, a non-issue.
JMHOs.
