Replying to Anon m2 vs electric eg2 ?

Hi guys, I want upgrade my goggles. I use electric EG2 and it is perfect for me, but it kinda oldy and lens are pretty pricey and hard to find in my city. So I decided to swith to something new. I can get m2 in same price category, looks cool + .
ziess lens + magnets.
Anon m3 is cylindrical, m4 has issues with optics and I dont like its design, I want something spherical with large field of view. Is anon m2 smaller then eg?

Any advice what goggles to go ?
