Yes, agree with you here.
From my personal experience, MPEG-2 keeps better the sharpness of the image & looks very good with high bitrate (>20Mbps). The problem is that with lower bitrate, it's too blocky (<16Mbps). H264 is less blocky even with low bitrate (+-10 Mbps), but, it sacrifices all the sharpness of the image.
Think it's about the way the codec filters the frequencies of the image. After all, the details of the image are in the high freq components (in a 2D DFT representation of the image).
