Welcome.
USB isn't inherently bad. USB is just a comm channel for computer data. The bigger issue is the quality of the card. What is it?
For USB, the ATI 600, clones, ATI AIW, couple others.
BTW, I still have a few available in the marketplace:

ATI AIW XP system is always an excellent choice. Those are my primary capture setups. But I have some USB as well, on Win7 systems.
More important than capture card is the full workflow: quality VCR with line TBC, external frame TBC.
Some of those also in marketplace, myself and others.
You're in the right place to learn about, and get, the equipment you'll need to do a quality job.
