Should i buy criminal or Crystal?

[abigL]

i have enough money for 1 criminal rank in prison or for 30d crystal rank which one should i buy?

depends what you play more or whether you want a permanent rank. If you are unranked on prison, I would say criminal is more useful.

My personal opinion would be to go for permanent ranks(in this case Criminal Rank) but it's your choice and it also depends which game-mode you are most active on as said by Sebocalypse above.
