Given the inherent complexity of video encoding and the lack of consistent standards, that's hard to do. I think it has the best balance between power and ease of use. As mentioned, it's really the same encoder with different interfaces. The encoder part is trialware and it's not as good really. Good program (it supports separate chapters) but it won't work with many newer discs. However, the last suggestion certainly isn't for everyone, since command lines tend to be a pain to learn. Or, if you really wanted to, you could manually learn the command lines for either. Is also common I think, but I haven't found it to be too particularly reliable.
I'll also use from time to time, as I see fit, since it has more powerful post-processing features. I mostly use, as it's simple straight-forward interface makes many tasks quick and easy.
