The new 2019 release MoYu Aofu GTS M is an exceptionally smooth and fast new magnetic 7x7 speedcube release.  The most noticeable immediate difference is the smaller size (68mm) which makes the cube both lighter and easier to control.  The stickerless variant comes with a a new half bright shade which looks great and is easier to recognise.  Importantly the GTS M comes with 144 factory installed magnets which are carefully inserted into the new magnet slots to provide maximum control and stability during solves.
