I’ve used both SlickEdit and SublimeText for a significant amount of time (12 months on SlickEdit, nearly 2 years with Sublime). Here’s my 2 cents (which Arjan will immediately discount). I read the drdobbs article, and it smacks of someone that spent a day or 2 on each editor. He discounts the code map on the side as eye candy, but I’ve found it to be extremely useful. It’s surprising how quickly I can just scroll to the bit of code I’m interested in just by it’s appearance visually. He also left off some of the most interesting features of SlickEdit, such as the built in versioning of edited files.
Also, his assessment of the cost is somewhat confusing. It’s not clear from the article how stark the contrast in costs is. With a single license purchase of Sublime, I can install and run on Mac, Linux, and Windows. For some, that’s not that big of a deal, but I support software on all 3 platforms, so I need something that will allow me to work on all 3. To purchase a license for SlickEdit that will run on all 3 platforms, I would need to spend $650 (that’s taken from their website this week). I got away with running SlickEdit for as long as I did by purchasing an educational license (I was teaching Computer Science on the side at the time, and used it in class for code demonstrations). If SlickEdit had shown itself to be worth the cost, then I would have figured out a way to either get my employer to purchase me a copy, or saved up the money to purchase a full license, though I probably would have just gotten a 2 platform license, and made do with Vim or something else on Mac (it’s the platform that I spend the least amount of time on out of the 3). In the end, I didn’t find SlickEdits code completion to work all that well, and some of the features that I thought were really cool, were also ones that I never got full use out of, so for me, it wasn’t worth the price tag.
I next tried Sublime. I stumbled on it from discussions of another textmate like editor that went defunct (e TextEditor). Initially I just used the trial version. I used it in my courses for a semester, and in my day job. I found that the snippets made me more productive (and my students were impressed as well, though it did confuse them initially that I’d type if, and suddenly a stubbed out if statement would appear). As mentioned before, I liked the code map, and a vim mode was an absolute necessity for me (both SlickEdit and Sublime offered it one way or another). The plugins available for Sublime worked well enough for me, and I’ve rarely had a significant issue or a crash, so after a month or 2 of use, I went ahead and purchased a ST2 license. I’ve been using ST2/3 ever since.
