- Load times both times only the upper (I watch yet)
- Plugging the controller sometimes tricky (please do not force!). However, this is also going into debt to simply lousy microUSB (who has invented this port please? Apple's Lightning shows how to do it better)
Say docking solutions at this connector work never perfect - ADDENDUM: they do it! -> "Lioncast LC20"
Conclusion: For me it is enough. Optimal is just different. (Wede observe it further if both controllers load)
