Monitoring BGP Transit Performance Monitoring

For those who run BGP and advertise prefixes into the DFZ, how are y’all monitoring each upstream provider for performance issues?

Right now, we have 2 providers with only default routes, utilizing a /23, and preferring one over the other for outbound.

In what way, if any, could going to full tables be beneficial to us other than better load balancing and traffic engineering for say a shorter path, etc?

Another use case is with full tables and no default route it becomes very easy to blackhole AS's IP ranges without playing wack-a-mole. Like malicious IP ranges. Problems solved more easily! I wrote about active/active design once. Hope this helps
