HPT is way more user friendly. I have heard and seen personally a LOT of the tables and general layout in the power tuner and it looks so out of date it's rediculas. HPT also has a LOT of additional ''histrogram'' tables that dhp does not. One very handy table is the main spark knock retard table.
What this is is when you have kr it tels you in what EXACT cell in the Spark table it is in and AND how much KR you were getting. Open up the editor and reduce the timing by the amount of kr that was showing up and BAM no more KR.
This is what is called a timing tune and is generally the last step in the tuning process.
HPT has a lot of other things that makes tuning Easier. Thats just a small example.
It may be More stuff to learn but you have more tools to use once you find out how they work. You can't ask for much more
