IMO, the third option should not be considered at all, since gdal2tiles 
is very important tool in gdal and many people (including me) prefer the 
script from any GUI out there. I have also seen an improved version of 
this script dealing with multiple threads.

My preference would be option 1.

Just my 2c :)
