How to judge a tripod.
Generally I would go with the heavier tripod of the two which appears to be the first one weighing in at 9 lbs vs. the 2nd one at 4.5 lbs. However, this is at best a calculated guess as I have not played with the head. Fluid heads can vary on smoothness, and the only way to really tell what's going to make the smoothest shot is the old 'A vs. B' test. This would require you to take similar footage with the same camera on both tripods and compare the results.
1) make a pan and a tilt shot for each with the widest angle lens.
2) repeat pans and tilts, continue to work the focal length with more telephoto, see which one is smoothest as you use more magnification.
3) take it outside on a windy day, see which one can handle the wind the best.
4) how does it feel? Is it easy to adjust or does it feel sticky and sluggish.
