I have tried both the X-man bell and the Moyu Magnetic pyraminxes and I use the Bell as my main. When I got this, I was blown away by the stability and the speed of the puzzle. The magnets are very strong, which supplement the speed very well. Overall, this pyraminx has a great feel that I think will appeal to many people, and my times are noticeably faster on this tetrahedron compared to the Bell. If you like the Moyu pyraminx, you will probably have a harder time switching to this because of the differences in magnet strength and stability. If you have the money, it is totally worth it.
