I didn't performed any comparison of libavcodec mpeg1 encoding and mpeg2enc. I added mpeg2enc because I wanted to have an MPEG2 encoder in ffvfw and when Nic released his mpeg2enc compile I tested it and it seemed quite good to me.

I don't know if I can make it faster. Maybe it'd be useful to replace mpeg2enc quantization and DCT routines with those from libavcodec, but I don't think I'm capable of doing this now.

mpeg2enc two pass encoding uses the XviD two pass code. I find it very flexible and using it for Theora too. However this code doesn't have option for setting minimum bitrate which would be probably useful for MPEG1/2 encoding.
In MJPEGtools CVS log I saw that the mpeg2enc developers are implementing their own two pass encoding routines.
