Look, there is not a one size fits all solution for DDoS. It much depends on the BIG-IP device you have, the TMOS version you run, the license you own and the kind of attack you see.

From the link you have shared, I would configure Behavioral & Stress-based Detection only. Do not combine Behavioral & Stress-based Detection with TPS-based detection.

Additionally I would add a Bot Defense Profile. https://techdocs.f5.com/en-us/bigip-14-1-0/big-ip-asm-implementations-14-1-0/configuring-bot-defense.html
