Advantage of AGI(Android GPU Inspector) compared to Streamline

Hi, I'm Android device developer, and using Streamline for checking Mali-GPU performance status.

Recently, I find AGI(Android GPU Inspector).
https://community.arm.com/arm-community-blogs/b/architectures-and-processors-blog/posts/total-compute-developer-access
According to this article, AGI is also developed by arm.

Q1
May I know advantage of AGI compared to Streamline from Mali-GPU Android device point of view ? 
I've checked that there are many GPU counters in AGI(System profiling) compared with Streamline, in case of  Mali G57 Android device. 
AGI : about 280 GPU counters
Streamline : about 80 GPU counters
If arm recommend to use AGI for Android device, I'd like to know the reason.

Q2
CUI command is supported on AGI like Streamline ?
In case of Streamline, I know that CUI is supported.(streamline_me.py and Streamline-cli)

Thank you !

Best Regards
