It's horses for courses, basically. As said, the Tdi is easier to work on due to its simplicity, whereas the Td5 has more electronical gadgets and such. The Td5 can be trimmed to provide more power with relative ease. Both engines have a few issues, but, as stated, most of these should have appeared and been rectified by now. Well documented service history is always an asset.
I have both, a Tdi (which I do favour) and a Td5 (which I initially was very sceptical of but have been converted), different characteristics, both reliable.
My 2c...
