Pre-sales question Extraneous URLS

I'm using OpenSEF right now and it gives lots of extraneous SEF URL's that I need to delete every week.

Does SEFAdvance do the same?

What are the advantadges of SEF Advance over OpenSEF?

My clients website has over 2000 articles and will soon have 4000.

I will not comment on other products or do the comparisons, maybe some users can do that.

As far as SEF Advance is concerned it doesn't save URLs in database so it's nothing to delete. All logic is performed on-the-fly so there is no possibility for duplicate URLs. Also the possibility for database issues are minimized, especially with its cache system.
