Question:
How to choose a FIWARE NGSI-LD context broker?

Description:
I need some help to decide which FIWARE context broker (Orion-LD, Scorpio, Stellio) I should choose for a smart city architecture. There is no existing component which uses NGSI-v2.
Is there any other reason why you should choose the Orion-LD context broker besides the fact that it is the only one that supports NGSI-v2?
Is there an advantage that the Orion broker is the main component of FIWARE?
The paper "Open-Source Publish-Subscribe Systems: A Comparative Study" says the scorpio broker is the most complete system overall.
The paper "Enabling Context-Aware Data Analytics in Smart Environments: An Open Source Reference Implementation" says the Orion-LD context broker is the most extended GE.
I also saw the performance comparison where Orion-LD is way faster at small batches of messages and slower than Scorpio and Stellio with larger batches.
Any suggestions?
Thanks!
