Some of the features offered by Crashlytics are:

• Instead of just showing you the stack trace, Crashlytics performs deep analysis of each and every thread. We de-prioritize lines that don't matter while highlighting the interesting ones. This makes reading stack traces easier, faster, and far more useful!
• Crashlytics' intelligent grouping can take 50,000 crashes, distill them down to 20 unique issues, and then tell you which 3 are the most important to fix.
• Now you'll get precise information on the performance of the devices that your apps run on. We'll let you know if the crash only happens on a specific model or generation of a device. We'll even tell you other information, like whether your app only crashes in landscape mode, or whether the proximity sensor is always on.

On the other hand, Crittercism provides the following key features:

• 30 Day Crash Summary
• Live Graphs
• Version Tracking

"Crash tracking" is the primary reason why developers consider Crashlytics over the competitors, whereas "Great customer support" was stated as the key factor in picking Crittercism.
