Alliance culture question

I’m a returning player looking to get back into a null corp. I have many years experience in the game but coming back after a long break. I’m just wondering if anyone wants to share the differences in culture between the alliances, like goons, Brave, Pandafam, Frat, and Init? Not looking for intel or anything just play style, seriousness or not, age culture, time zone (especially Asia and AUTZ). Anything to share to help me decide?
