To go back to your original question I would first ask how large your railway is going to be, a shunting plank OK you can glue but as the layout expands this gets more difficult. Complex junctions demand set up accuracy and glue but then get it wrong is an issue, if you need to adjust for some reason then the glue becomes a nuisance and ballasting never looks as good again.
You might easily find a point problem such as a spring failure or you want to go electrofrog it all just gets messy, the alternative is to go track pin, now these come in all sorts of sizes so I use an intermediate size and never the Peco easy bend, so my track sits on Noch-Guagemaster gritted underlay and I pin sparingly, the only issue I get is that as trains run along they depress the track a little and over time pins can work loose so it takes a tap to get them home again.
Then again I do have complicated track work and if needed I can shuffle it to get better curves fit extra features etc.
I am certainly pleased with the look here although to achieve the 1962 'look' I am now ballasting between the track ballast, anyway this is a complicated junction and it slowly being switched to electrofrog without any detriment to the look.
