Moving off of data center security/networking products to AWS offerings?

Has anyone switched from data center security/networking to AWS offerings?

i.e. F5 to AWS Load Balancer, Palo Alto FW to AWS FW, Imperva WAF to AWS WAF?

I'm trying to get an idea of how mature and flexible the security capabilities in AWS are compared to other security products. If anyone can share their experience with limitations, pros and cons, etc., that would be great.
