what site map do you recommend

what site map works  great with sef advance and google site map.
any suggestion is very welcome

Joomap seems to work fine. As for Google sitemaps component I haven't tested them but I'm sure there are some good components compatible with SEF Advance too.

I'm curious about this topic as well because Joomap actually worries me a bit. At Joomlas extension site, Joomap hasn't been updated for over a year and some of the links are broken (Download & Homepage).

I'd really love a robust sitemap generator for my main site but the pickin's seem mightly slim at extensions.joomla.com

Which sitemap are you using on this site?

This is not Joomla site. It is customly programmed site, including the sitemap.
So I wouldn't know, the Joomap is what I heard one of the best, but again, I don't use any of them.
