In my opinion: both plus some Ryegrass...
Northern mix with 85% TTTF, 10% KBG, and 5% TTPR seed by weight. Ryegrass and Tall Fescue are very wear tolerant, so don't omit either. Best of all worlds. Big upgrade over KY-31, but nothing will likely be tougher than KY-31.
Allows for quick and easy repairs via seed, and is super tough once established for several years. Repairability via KBG rhizomes as well.
FYI, this is also roughly the same mix that Pete from GCI has in much of his home lawn.
That 5% (by weight) ryegrass often makes a huge difference in durability and repair ease versus just TTTF/KBG, believe it or not, due to fast germination and its density. The only reason to omit one species is for looks instead of durability (if uniformity is more critical).
No lawn will tolerate digging or urine, though.
