Yes, esyndicat is another great directory script, and I would say is the #1 competitor of phpLD. I think competition is great and helps both scripts strive to offer something more.
We are now about to release version 3.0.6, which I am very excited about.
One of the more notable items added to 3.0.6 is support for Paypal Subscriptions, which I hope will allow people to better leverage a monthly revenue stream.
Also, it is a lot easier now to "mass edit" (delete or approve) links (yipee!).
Another cool new feature is the option to use the new Ajax Category Selection mod.
Anyways, I think both scripts are great, though I hope you will pick phpLD. :)
