Both are higher than is ever recommended, but it’s what I like, and isn’t that what matters?
Well in addition to "what you like", there are also safety factors to consider. For example if you are using hookless rims and you exceed the maximum pressure then you could have a sudden blow-out. So at the very least you have to know what the safe limits are for your particular tyre/rim combo.
