This is seriously not only about taste.

A Link to the Past beat Minish Cap by a long shot. Not because Minish Cap was bad, but because A Link to the Past was so great. It had more difficulty, more temples, a larger area to explore.

But to show why it IS really better let's weigh the facts.

Arguments for A Link to the Past ( correct me if any of them is wrong ) :

- A Link to the Past has a larger world then the Minish Cap.
- A Link to the Past has more temples then the Minish Cap.
- A Link to the Past is more of a challenge to beat.
- A Link to the Past was a lot more of a breakthrough.
- A Link to the Past has more items and possibilities.

Arguments for the Minish Cap ( correct me if any of them is wrong ) :

- The Minish Cap has slightly better graphics then A Link to the Past.
- The Minish Cap has more sidequests.
- Becoming Minish.

I probably didn't list all the possible arguments on both sides, but this is why I find it obvious to choose for a Link to the Past.
