I really enjoyed the GBA version and would really recommend it to you. As a fellow Brit, my first experience of FFVI was the PSX version and I'm slightly stunned to admit that I completed that version. Perhaps I was a masochistic 12/13 year old or something. GBA version, however, has nice extras, is nice and smooth and an improvement over the original really. Only complaint is the lack of Son of Submariner, but otherwise it's well worth a whirl.
