I'm using opensef on that site with glossary. I got someone to make me a sef_ext for it from joomlancers.

I still use Joomsef for a lot of my sites but I have to use Opensef for that one because Joomsef has problems with the 404 logs creating URLs that don't exist and that site has hundreds of pages so I couldn't keep up with all the error log mistakes.

Opensef is a pain because you have to click the links to make the URLs, which takes ages if you have hundreds of pages, but it doesn't fowl up on the error logs and it doesn't create differntly named URLs if you have more than one link to a page from different menus. Joomsef gets around its item ID problem sort of by allowing you to ignore item IDs, but if you do that the site wont work properly.

Ideally I would like a combination of Joomsef and Opensef, they both have good points that the other doesn't, and I've donated money to both of them. The coders on both scripts though are very slow to respond to anything, even when you offer them money, so it gets frustrating after a bit if you want anything fixed properly. I donate money to one and wait, they do a couple of fixes but not everything, then I get tired of waiting and try the other one instead where the same thing happens.... so I just muddle through and try to get sites to work with Joomsef or Opensef the best I can, whichever one I think will work closest to what I need it to do.

If I was a better coder I would do it mysef. :)
