Perhaps these excellent publications by Justin Pietsch can help you decide: https://medium.com/the-elegant-network/performance-testing-of-commercial-bgp-c3b93424dd6d I suggest reading the entire set of posts.
I don't know if anyone has done analyses of this same type recently. If so, I'd like to read them.
