I gotta say - I like the Ultimate TinyMCE better than WP Super Edit!
They have the same functionality but the TinyMCE seems to work better. Sometimes the font selector wasn’t showing up on WP SE and sometimes it works fine - rather than try to figure out WHY it is easier just to change it out.
The configuration is more streamlined so it’s faster to pick and choose what you want to show. To me ANYTHING that makes a process faster is a better choice, time is money!
