Whom do you prefer, your sister(s) or your brother(s)?

I have 2 brothers and one sister all just half. My sister is the only one I talk to. My brothers don't like each other, actually none of us really like each other except sis and my one brother. We all had very tough childhoods my dad was the biggest prick I've ever known and that's saying something.. So I prefer my sister but she's rotten too I know but the only family I have left so I have to let go of the wrong she's done to me..
