The two are very different, comparing the two in terms of overal would be a matter of opinion, because both things have their pro and cons in equally states and is quite oposite to one another. It would be easier if you want to compare them in terms of one particular aspect instead of overal, untill them there is no really a right answer, both people who say normal or pychic (or even both) would be right. (Because they have different playstyles, what is better for one is worse for another)
In resume, in terms of overal they are equally related, have their pros and cons about the same, however the people who does more one thing than another will have a easy way playing with a particular type over one of thoose, but that doesn't mean that type is better in overal, it just mean that, for that person in particular this works better than the other.
Hope i helped, have a nice day!
