Asisde from both being friction drives, they are very dissimilar systems. Big weight difference, Alizetti's system isn't intended for fast removal to prevent theft when you lock up your bike. There are other differences but those two are prettty major. If you're okay with a semi-permanent install and not weight conscious, it's a fine solution. But at least where I live (big city) I'd be concerned about leaving an expensive e-bike system locked up with my bike since it can easily be removed with some basic tools.
