What he is saying has a direct result in the statistics. Nearly all of the good JK levels were built in JED. In fact, I don't know of a single good level built in JKEdit (I remember a news post about one, but that was at least 2 years ago).
I mean, 99% of the people here are telling you to switch to JED. Why do you think is that? Because we are all fuzzyheads that simply don't like JKEdit without any reason?
This editing community has over the years worked hard to push JK to and beyond it's limits. The people here know what can be done, and what needs to be done to achieve any editing goals. And they know what tools to use.
If you stick with JKEdit you are either lazy or an ignorant.
