Theres always a but.

Ill get the negative out of the way first.

Layout!

Garage Band has two screens, one consists of a track view that shows you all the instruments/ vocals / mix downs that are in your current track. Its displayed quit nicely actually and is easy to navigate around and tweak. The second screen it provides is one that comes up when you are in an instrument mode for any of the tracks from the first screen. Here is where you can play and record your instrument of choice. With Thumb Jam however, its just sloppily pasted over your screen where your instruments notes are shown. Its quite messy and just gets in the way IMO . If there is a way to not have this show I have not come across it yet,nor should I have to search for it.

That aside , the lavish assortment of instruments and the quality sound these instruments provides is fantastic. And the ability to create your own instrument is fantastic! Not even the mighty Garage Band can compare to the variety and quality of these samples!

So do yourself a favor and pick this one up. I have both because I find they differ enough to warrant having two capable music apps at my disposal, but Thumb Jam takes the cake for instrumental variety!
