Trumpers is more traditional and doesn't have a leather note. Rather, it is supposed to evoke the perfume that new leather used to be scented with back in the day. T&H is modern and rich, with a strong leather note, but reminds me of a department store fragrance counter.
For the record, I own Trumpers. But lasting power on it is weak so I use it mostly as an after shave cologne.
If you like T&H Spanish Leather edt, you will like Zino Davidoff edt equally well, at least in my experience. Perhaps even better because Zino is less expensive.
