It is a very interesting route I really liked playing it on TSW2020. I have not touched it in TSW2 yet, since the sound of the locos are terrible and it is unplayable at the moment. The other advantage of having that route is that it will add new layers (and thereby traffic) on other German routes as well, the BR146 and Dostos are used on pretty much every route released after MSB, so it is definitively a recommendation!
yes spend your money on this plenty to do and dont forget to get the german shunter for this route as well. money is well spent on this route
