I like that it can be used with any simulator, not just AIMSYS or PSAVE! It's easy to use - everything you need in one place (including tutorials!).
The fact there are multiple ways of running simulations makes things easier than other simulators where only 1 way exists; but this could also lead people into thinking they should choose their own solution instead if using an existing product which has more options available as well? There isn't much else really worth saying about lannerswitness apart from its ease-of-use compared to some others out here who seem very closed towards customers/users so don’t have many features included at all etc. Not sure what i was looking forward too when purchasing lanners witness however after having been through training videos provided by them along side my project manager we were able run our first testcase without issues whatsoever.
