They aren't really comparable. While IDA has some debugging features, it's all about static analysis. It has features for browsing and annotating code - you can view the code as a control flow graph, add your own names and comments to functions and variables once you've made sense of them, define structures and their members so you don't have to memorize what each offset to a common type means, jump around in the call graph, find other usages of global variables...
