>I don't really care if its open source or not if it does what I want it to do

You care about the utility of your editor, and that's fine. Several other comments here try to highlight ways in which open source projects are more pragmatic, like the ability to make modifications yourself or take advantage of community contributions.

All of that is just arguing about utility, though. For many people open source is a moral issue. RMS is a notable example here. And I prefer open source tools for this reason.

If you believe open source software is morally superior to closed source software then the utility considerations are of secondary, or perhaps even zero, importance.
