ANDROID Which is the most feature-rich and stable release?

Hi

since I've had to be very busy the last months and wasn'ta able to follow these threads I think I totally lost the overview of the right NextGen Release.

Perhaps, maybe or hopefully someone can help me a little bit for finding the right one, please

Which version of those many NextGen releases here is the

• most feature rich (Android TTS, OnlineTraffic and perhaps Search-Enabled but no other requirements)
• most stable
• has the most recent maps for at least europe

Thanks is advance!
