is it worth it?

BNSF1995 - Surprised you don't also have an issue with those dreadful, ancient 2D trees and shrub splines brought over from the Ark.
Fortunately, TRS19 looks nothing like the above with proper attention to using the latest route-building methods, tools and assets in Surveyor.
Some legacy assets look - and perform - worse than others - whilst some actually look better - but it mostly pays to use more modern equivalents...

It is very good. I created a dilapidated garage with over-grown grass and weeds, some iron bars, an old rusty windmill, and some more junk lying around. I printed out a screenshot and showed it to my wife. She thought it was a real picture and I was going to try and create it in TRS19. It looked that good. So, yes, it is definitely worth it for me.
