I realize that, but I guess what I'm asking is what is worth more? 1k Virgin points, 7k Hilton points, or 2k miles on AA or Alaska?

I earn $100 e-rewards about 3 or 4 times a year.

I have been putting them into Virgin, because I like their airline, and they now fly to Maui, but the rate is poor ($100 for 1k points), it seems.

I used to always get Hawaiian Miles, but they are no longer in this program.
Hilton has devalued their points so much, I'm not sure if 7k of them is equal even to 1k Elevate points.

Alaska has a nice program, and they fly out of my local airport (Charles Schultz), which is a plus, and I can go almost anywhere with AA miles, and SW goes to PR now, I think, so I'm just not sure which program to choose
