Here are some comparisons:
VCI's first DVD:
VCI's second DVD:
A clip from ATTACK OF THE 50FT MONSTERMANIA (shown on AMC):
And the MST3k version:
The VCI transfers are heavily cropped on the top & bottom. However, the first release has more information on the sides. The second transfer has more information on the left side, but LESS on the right side, and even less on the top & bottom!
The AMC clip looks superior, with more detail, and less murky/bleeding colours. And finally, the MST3k version has a tiny bit more information on the top.
I love this movie, and I'd really like to find a decent transfer of it (C'mon Warner Home Video!).
