Packet Loss and Ping (servers)

I had a question. 

I decided to try the Tokyo server last night since it always has a lot of switch players and it seemed to be running better than the Oregon server, and it had zero packet loss when Oregon was showing 2.

Does this make a difference?  I've noticed some have high ping, but show no packet loss.  Sometimes Oregon server has the lowest ping, like 68 or so, but has a packet loss of 2.

I was wondering what the difference is and how should it reflect our server choice?  When I tried Tokyo I could see the enemies better and it seemed like I was moving faster, so I'm wondering if packet loss being zero could have to do with it?

Is zero packet loss better even if ping is about 120?  Anyway, any advice would be appreciated, I don't really understand much about ping or packet loss except that it has to do with internet speed and router communication.
