Actually I guess the picture quality would be a valid question
for an NTSC tuner. I had missed the fact that the OP was
looking for something that did both NTSC and ATSC (for which
the picture quality question doesn't really apply).
For ATSC picture quality is going to be the same for all
tuners. The question is how well the tuner and demodulator can
handle multipath and low signal strenth. With ATSC you've
pretty much either got a picture or you don't.
All USB NTSC tuners are going to to hardware video encoding.
USB just doesn't have enough bandwidth to send uncompressed raw
video (that would require real, sustained usable throughput in
excess of 200Mb/s).
