We don't run a competition about being the best CMS - although we do our best to make XOOPS the best available (just like the Xaraya devs try to make Xaraya the best, the Mambo devs try to make Mambo the best etc.) and we most certainly have great respect for the work accomplished by the Xaraya team.
They are doing things their way and we do things our way - I believe that XOOPS' way is the best, but Xaraya does have some good things, which could be good to have in XOOPS also.
