UltraEdit is well suited for editing very large files. The macro editor is very powerful and easy to use. If one needs a quick-to-open text file editor, you will find UltraEdit much too slow to load. Compared to some free editors on the market, the basic individual user license is quite expensive.
I would recommend Vim in any scenario where text files have to be viewed, created, or edited on GNU/Linux computers. Regardless if you need to quickly change a few things in a configuration file, or you need to write up a full document, Vim is great. I wouldn't use Vim to view, edit, or create anything that requires "rich-text". In other words, if you need to format the text (bolding, font colours, word-art, etc), then Vim isn't the tool to use.
The color coding capacity is rudimentary and keyword based only. A good color coding mechanism should allow context.
With the latest versions, the top menu has a lot of big icons and has a user-friendly kind of look which impacts the actual text window. Most users don't fancy pretty icons and like efficiency over pretty buttons.
As a program UltraEdit comes ready to use out of the box and requires very little setup for it to be extremely useful. It's flexibility among a wide array of tasks and files makes it a go-to for all our troubleshooting and data viewing needs. Timely updates and great support.
I don't consider the steep learning curve to be a hinderance on the overall usability. I would rate this a ten, but to be honest a lot of people do get hung up at the beginning and just abandon it. However, for people who have made the moderate effort to get over the hump, nothing can be more usable.
There is no commercial support for Vim. Thus, it will not get a mark beyond 5. However, community support is very good. You can easily find solutions for most of the problems in the community.
I have evaluated Notepad++ as an alternative to UltraEdit. In some cases, such as loading time, Notepad++ is a superior product. However, in terms of editing existing macros, and editing very large text files UltraEdit is a much better product.
Vim's keybindings are a lot more complex than Notepad++. With that, comes a whole bunch of capability that Notepad++ just can't match. Emacs is comparable, in terms of capabilities--because Vim is built into so many unix systems, I chose to learn it instead of Emacs. Knowing both probably isn't a bad idea, but there's enough to learn in either camp to keep you busy
