RR&Co is, as far as I understand it, a very comprehensive piece of software. It is also very expensive. JMRI does a similar job and I use Rocrail and it does everything I need it to. Both are free although rocrail does encourage a donation.
I have used Lenz equipment for years and have occasionally thought about changing. I have always decided against it because my Lenz equipment works, I am familiar with it and, again, it does what I need it to. Clunky, perhaps, definitely not all the bells and whistles of some newer systems. but comprehensive features.
