I don't use Lytec, however there's one more important point to add. Lytec is one of the oldest and most well-known PM systems around. They were around a few years even before I started in 95 and rarely do you hear anything negative about them. Their name and reputation are very trusted. i believe they are now owned by (have been for a while) NDC. I could be wrong about that though. When shopping for software having a name that has been around and associated with trust and many users available sure goes a long way in a tough decision.
