Hi Chal I have the mag, minix and vixo. I would say it depends if you want to use kodi stay away from the mag you won't be able to do it. Other than that the mag is a solid choice and woks well.
Now for the avov and minix the big difference is being able to to customize the minix is open source while the vixo is closed source meaning you have to wait for what the mickyhop guys put out but you can have kodi on both systems. The vixo seems like a better unit to me over all if you are going to spend 150 for the minix spend the extra 30 and get the vixo 2 just my humble op.
Good luck let us know what you decide!
