It should be noted that SquishIt works differently than Combres2, so itβs not easy to produce better code.
SquishIt works great with T4MVC, which you wonβt get Combres2 with. Based on this, I would tell someone to use SquishIt. In addition, SquishIt is not an xml config file that allows for more flexibility. In fact, you could theoretically create an xml configuration file and simulate Combres2 if you really want to.
In terms of minimization, SquishIt is actively developing, which means that if new methods are created to minimize the scenarios, you will most likely be able to use this. It currently supports JSMin, YUI, MS Ajax Minifier, Closure Minifier or even no minifier.
Update 1/18/2012 : There are now many other alternatives besides SquishIt and Combres2. First, Microsoft is creating its own system for the next version of ASP.NET 4.5. Cassette , similar to SquishIt, and RequestReduce , which is completely different from everything else, automatically doing everything for you.
