I actually like the older ones better. Yeah you're sacrificing half the space for text, but there's something about the design and flow that makes me prefer the first set.
However, if I'm looking at a bunch of your thumbnails at once (say on your channel page), I think that the second set might look better because the crescent-shaped background for the text in the first set would grow repetitive. One at a time though, I definitely prefer the first set.
The "Lost Trigger" watermark on the first set is not needed though. Too small for anybody to ever notice it and it just clutters the image.
