Lemon Meringue Pie or Key Lime Pie

It is the last full day mom is with us and we ended up at some Turkish restaurant which happened to serve a South African favourite, Lemon Meringue Pie. This bought up a time long question I have wanted to answer, which is the best Lemon Meringue Pie or Key Lime Pie, but never got round to tasting a Key Lime Pie so I am starting to wonder if this question would ever be answered in an unbiased way.

So these are my questions...

1. Who makes the best Lemon Meringue Pie?
2. Where can I get a good Key Lime Pie so that I can use for a taste experiment? 

I am based in Johannesburg, so I can't get to any exotic places where some of you live unless you can courier a pie to me. Anyways I love a good lemon meringue pie but can't wait to experience why some make a big fuss over key lime pie.
