Secret of Evermore: Which Version?

[layzee]

I mainly collect Japanese-version games of games I like. I like Secret of Evermore, but that game wasn't released in Japan.

So I have two choices: The NTSC-U/C (USA/Canada) and PAL (Australia/UK) versions.

Which should I get?

PAL version pros:
- Super Famicom-style cart
- Possible bug fixes

PAL version cons:
- 50hz
- Possible black borders (above and below)

NTSC-U/C version pros:
- 60hz (i.e. full speed)

NTSC-U/C version cons:
- Ugly-style cart
- More existing bugs if the PAL version had bug fixes

I assume the Australian and UK versions are the same, apart from different regional details in the manuals.

Note: I own a Super Famicom but have no plans on getting a PAL or NTSC Super Nintendo.
