Ive used a few in my time, Air Data, Rodos, Jet Planner, SITA and now LIDO.
Although each have their "quirks", LIDO is a good system, database can be a bit tricky to manage sometimes and some of the set up procedures for writing rules could be better, but on the whole, I would say the best of the bunch and generated routes are probably 90-95% RAD compliant routes.
If you want some more info, you can PM me, been using LIDO for a number of years now.
