I don't believe there is one particular type that is worse. It varies based on the individual. Some say BP1 is worse than BP2 based on the manic side and increased likelihood of psychosis, but I did find an interesting article a while back that discussed how BP2 can be just as serious, and the depressions can be devastating and longer lasting than other BP Type 1 (though that's not true in every case, of course). I think they each have their own set of challenges, and everyone is different.
