ISerializable hates CodeRush
I thought this writeup was kind of whatever, at least as far as the author's concerns about how DevExpress presents CodeRush relative to the competition. Personally, I just care if the tool's any good, lol. Anyway, it's not much of a comparison, but there are other views about CodeRush out there and this is one of them.
Frankly, I came this close to buying CodeSmart about 18 mos. ago, but it was buggy as hell and could repeatably crash VS .NET. So I stuck with VA.NET (which, far from having no value, is actually a pretty useful tool). To me it didn't save enough keystrokes even without it's stability problems--it had some nice wizards and other GUI features, the templating and code builders were underwhelming (I couldn't customize them to meet the current code standard I was working under).
To me the far better templating/expansions and extensibility of CodeRush makes it an unfair fight. Then again, neither of these blurbs is a substitute for trying both tools yourself.
