I'm confident this is going to come across fan-boy like.
I definitely am not receiving a kickback from the TifTuf growers. Keep in mind, I sprigged my lawn for financial reasons.
TifTuf is significantly more shade tolerant (keep in mind, it's still bermuda) than Tifway 419.
TifTuf is more resilient to winter kill damage than Tifway 419.
TifTuf greens up sooner and stays green longer in the season.
Color and blade width of Tifway and TifTuf are similar.
Better drought tolerance than Tifway 419, Prince 77, Celeberation, and Lat 36.
TifTuf uses 30+% less water than Tifway while maintaining a better quality turf.
Superior traffic tolerance to Tifway, Tifgrand, Tifsport, Patriot, Celebration, and Discovery
Sod strength is superior to Tifway 419
It establishes and recovers quicker than Tifway 419.

To me the contenders are TifTuf, Tifgrand, or Lat 36.
I think the choice comes down to where you live in the country (temperature/weather/climate), expected use, amount of forecasted shade, and anticipated HOC.
I cannot think of an area where Tifway outperforms TifTuf, so I can't really think of a reason to pick Tifway over TifTuf.
If you're going to be cutting with a reel mower below 1", Tifgrand might merit consideration.
If you don't want to have to cut frequently, Discovery should be considered.
