For me, it was between 1 and 3. However, I found pros and cons in each. 1, I adored the editing, it fit the mood of the song and was very sweet and perfect for valentines day. 3 made me laugh, hard, and the editing was also a total win. My god, the drill. *facepalm* Overall, both were great, but I had to go for number one (which surprises me because I try to avoid Kataang, but this just won me over, it was very sweet ^_^) simply because the sometimes the images contrasted with the colors in 3 were a little hard to make out. Great job to both artists, I was very impressed.
Even though 3 was absolutely hilarious, the colors were sometimes way to out there and made it hard to tell what was going on. If that had been done better it would have undoubtably been my pick. 1 was very well edited, song was great, etc etc praise etc worship. So I voted for it. :3
