If I have to choose only between those two, my pick would be:
Video No. 2 by @riverstyx
Although I like the animation as the all the graphics on video No. 1 way more, the music is extremely irritating. Another big minus is poor English. I mean, what kind of a question is: "HOW IT USE?" There are some others too.
In other words, if in that first (No. 1) video the music might be changed with some more appealing sound, and if someone would make grammar, spelling and general proof-read and necessary corrections of the textual part of the video, in that case, I would rather go with No. 1 than with No. 2. But if it is "take it (as it is) or leave it" case, then I would go with No. 2.
