I guess it boils down to, you are a lover of scenery and structures, watching switches come and go, seeing the winding track work ahead, seeing the station/platforms go by, hills, running through bridges as you command your locomotive.
Or you like that vantage point/rail fan view. For me I like watching a steam loco pulling a string of cars, rounding a curve watching the loco slowly make it over a curved trestle, side rods and all the side linkage whirring around......its a mechanical work of art. Or a loco passing through a girder bridge and disappearing into a tunnel, soon to reappear on the other side. I can then imagine myself sitting in the engineers seat with all that power pounding the rails , the throttle in one hand and the whistle cord in the other.
No matter which school of thought or preference you may have, it is ALL good. Nothing like model railroading. Enjoy it while we can.
