I'm not overly keen on any of them, sorry. But that's just different tastes I suppose.
Of the three my favourite is the superdry one, it's nice enough if a little boring. As a brand the stuff is usually good quality but 'cause it's fairly plain I think you'd be paying for the logo.
I'm about the same age as you and I'm sorry but I think the other two are quite frumpy and old looking imo, though I do like the colour of that seasalt one. Maybe try some 'younger' shops, river island, topshop, asos etc?
