I'm a total newb in lightning development so I don't really have an opinion. I'm reading Andreas, Olaoluwa and Pickhardt's "Mastering the Lightning Network" currently and testing out different implementations using Polar. Based on that small piece of experience, I currently like LND best but we'll have to see when I actually try to build something with it.

This is also why I ask, because I want to see other devs reasoning for going with one implementation instead of the other.
