TerraGen vs. L3DT, thoughts and opinions

I hear a lot about the differences between L3DT and TerraGen. Of both of these, which one do you see if the better terrain generator, and why? Just state your opinions, and make sure to note what you think the pros and cons are of each one...

I would say, out of the 2, L3DT, just because it's aimed more at in-game use. Terragen is mainly used for photorealistic images. Plus, the free version can be used commercial, where as a commercial license for TGN is about $80 I think
