150-180 My Golden Ping

I live in the Caribbean and I play on the NA server. Now as my title says I play with 150 - 180 ping when my ping is what I consider 'crispy'. Now I hear about people who actually live in NA play with 30 - 40 ping and people often complain about ping of 70 - 80 saying it's too laggy, or when it reaches 100+ they have to stick to CO vs AI. So I would like to ask whether you can actually feel the difference between 30 ping and 70 ping? Or have I just gotten really accustomed to playing with my 150 ping. Cause I don't feel as if it is laggy at all with 150 ping, actually I find it extremely responsive.

Also on a side note is there anyway to reduce ping besides moving closer to the hosting location?
