What are the wysiwyg editors that have proven to be reliable at large scale?

I recently heard that jWYSIWYG editor isn't a reliable editor for a large scale website. Are there other WYSIWYG editors that have 开发者_StackOverflow社区proven to be reliable on a large scale?

Thanks, Walker

These have a pretty solid and respectable large-scale userbase.

Since JS-based WYSIWYG editors works on the client side I believe they have not much to do with web applications scalability. The only important thing is maybe code size...
