I've tried many over time and some editor developers stay flat lined with no advancements while others who did well no longer do well and of course on the flip side I have seen others not do well before but do better now.
Overall, I just moved from a paid editor extension (no names to be mentioned here) for the JCE one. I have to say it's been over a year since I last used JCE but took another look yesterday and decided I like this version a lot better. Well done on this one and thanks Ryan.
Although now that I am on joomla 1.5, I am hoping the developer will push for the Joomla 1.5 Native version and not legacy because I refuse to run anything in the legacy mode. So in the mean time, I will have to use google's method.
