I use it, it runs very large FBSP maps, and the lightstyles work well enough for me... and I also have old hardware (Geforce 6 series). FTE performs similar to QFusion (while Darkplaces runs a lot slower on my rig). FBSP also has higher resolution lightmaps than normal Q3bsp or rbsp. It simply looks better. I reported on my recent FBSP experiments at my blog.
Regarding the latest stable QFusion, are you really going to use a three year old engine instead of the very recent Warsow version? Much the same goes for MD3 vs IQM
