Vendors listed there have pretty competitive pricing for bandwidth.
I find many AWS services to be priced decently (if you are using them properly, elastically scaling, etc). But that's definitely not the case for bandwidth. AZ to AZ charges are one of the worst - yes that's cheaper than egress but that's no consolation because you are essentially required to use multiple AZs if your business actually has any availability requirements.
And don't get me started on NAT Gateway pricing...
The Cloudflare Bandwidth Alliance is fundamentally a publicity tool for cloud vendors. Because most partners still haven't fulfilled their promises (including the founding members who joined in 2018). Their status is always something like "all bandwidth between X and Cloudflare will be free of charge in the upcoming months". Until one day some of them quit the alliance, such as DigitalOcean (IPO) and Linode (acquired by Akamai). So, just don't trust any of those alliance members.
Unfortunately the "Bandwidth Alliance" is too ambiguous for my liking. It requires both parties to be transparent and have clear ToS, and no limits, etc. In practice, it's simply not worth it. Source: myself trying to "beat the system".
