OK, I am a C4D user and I am biased (and haven’t used most the others). The general vibe seems to be that C4D is the best option at this level. Relatively easy to learn and get into, great cross platform, fast rendering – important for motion graphics. Its perceived weaknesses, those areas where Maya scores such as advanced character animation, programibility, and specialised add ons for certain high end effects, are not really applicable to motion graphics.
Also possible to export renders to AE with seperate channels as an AE comp. If you are on the Mac your choices are more limited anyway (no XSI or studioMax)
