Aside from Titanium, we also looked at MonoTouch[0] and Xamarin[1], which I believe (didn't completely read through) is built on both Cordova and Mono.
If you were building from scratch, maybe another one of those would make sense for you. We are working within an existing project (mixed native and webview), and Cordova seemed to best fit our requirements there.
