Yes. I can't find any technical comparison or performance test comparison. And I see a lot viral advertising focus on how bad is Edxposed (Without proof) even personal attacks on one of Edxposed dev and how good is Lsposed (Without data / comparison) in Chinese on Chinese web site like Zhihu and Bilibili.
It's open source yes. But even you are programmer and understand source code very well. Sill you may not have enough time and energy to review all code in every change and review it fast enough. That is why last year one of Lsposed dev make a "rm -rf" prank to Edxposed that no one find out in advance and warn everyone. Then cause some people to lose their data.
So, I choose something or not mostly depend on trust. But bad advertising and prank like this really didn't help.
