The clearest Modern-versus-Western distinction is fastening: a button front and one zippered chest pocket versus a pearl-snap front and two snap chest pockets. The same listed 60/40 blend does not make the cuts interchangeable.
Shoulder reports make the first try-on different
Landy found the Modern tight at the shoulders and shorter than expected in his usual XL. Tom found the Western comfortable around a broad back and underarms where other flannels bothered him. These are different people, not a controlled fit trial, but they identify the body areas worth checking.

The better closure is the one you prefer using
Bryan specifically prefers the Western’s snaps. Ryan likes the Modern tucked or untucked and finds it light with some warmth. Neither comment proves that one fastener lasts longer or that equal “90 g” wording means identical fabric thickness.
For an opening outer fleece rather than a flannel shirt, the sweater-versus-Camp comparison addresses a different layering choice.
