Not necessarily, but in any case mplayer's options can be easier to control. I've got plenty of experience with it, and the mencoder companion app.

...in a perfect world. But MP3 files play everywhere, and LAME in "--preset standard" mode produces a dynamic VBR (variable bit rate) file that is, in my experience, indistinguishable from the original.

Precisely. I'm not an audiophile, and based on testing my ears have already pretty much lost frequency response above 14KHz, so absolute audio fidelity is not my priority. Something that can play in any device I throw it at, is. Plus there are tools like mp3gain which allow fully-reversible gain adjustment. The AAC format, for example, doesn't offer that.
