I prefer coffeescript for the reduced line noise, particularly around lambdas, loops/comprehensions, and object literals. I find the shorter lines and reduced line count* allows me to notice api flaws more easily, so I tend to do my api design in cs. I generally don't use the class construct unless the library I'm working with uses the same pattern (e.g. yui3). It's pretty much just syntactic sugar that simplifies the code at the expense of complicating the toolchain. I think it's worth it but I've met plenty of people who don't. * In js->cs rewrites I usually wind up cutting the line count in half, but most of that is eliminating all the stray closing brackets on their own lines and collapsing if statements into single lines.
