Psychology of Poker vs inside poker mind

[Montrealcorp]

hi,i just want it to be clear in my head since all i know is only bit of memory, i want to be sure to have it right!

wich one is better?
i remember(correctly?) about reviews that were saying:

inside poker mind is much better then psychology of poker and if u had to choose between the 2,inside poker mind was the one to go?

so,is this right or not?

furthermore i did buy it (inside poker mind) and i found it great.
but,is psychology worth to get anyhow since i already have inside poker mind?
is psychology of poker bring info that poker mind didnt cover already in it?

ty for answering
