I love tomato juice, so I would probably like v-8. I haven't tried it in years, and I can't really remember. I just have this mental thing about drinking my calories (even low calories). If I do it, it is as a treat. Actually about the only time I get tomato juice anymore is on an airplane.
There are very few days that I don't get my veggie servings in. Usually hunger forces me to, even if I'm not in the mood. I just find the whole vegetable so much more filling than the juice.
