I looks a lot like the GoPro Hero3+: Black Edition (See side by side pics)
However there are some differences in specs. The main differences are that the SJ4000 doesn't have wifi and cannot record in 4k or 2.7k. Here are some more specifications.

As you can see the by the specs SJ4000 DV Camera will not replace the GoPro HERO3+: Black Edition pound for pound, HOWEVER considering the price of the GoPro HERO3+: Black Edition at $499 compared to the SJ4000 DV camera at ~$93 you can see that the SJ4000 is the smarter of the two buys and at that price you can buy FIVE of them and do more than you would be able to with just one GoPro HERO3+.
At the least you should consider the SJ4000 as a backup camera for situations where you would hate to lose a $500 camera but are willing to sacrifice a $95 camera.
