Favorable rake structures for $0.5/$1 and $1/$2

[Roadstar]

Has anyone taken the time to compare the rake structures of different online sites for $0.5/$1 and $1/$2 limits.

I was surprised to see that Party's rake is a lot higher than, say, Pacific's when the pot is just over $5 (pacific is $.25 while party is $.5). Once the pot becomes sufficiently large ($20) then the rakes are exactly the same.

Any thoughts?

Thanks!
