To be absolutely safe, choose 4-5 of the ideas, track all of them and use a

You can find a lot more details (including the oscillating routing problem)

I think that "good" is all relative to what you are most likely to be
able to reach from wherever your location happens to be!
Google's... Level 3's. Root DNS servers (anycast) Pick something.

Make sure you source your icmp-echos from the address on the interface
facing your primary ISP, otherwise your routing table will oscillate
