I think either class sets work, Lord T's is something that would definitely destroy many of the melee standards set in the PHB; which from all the "Fighter Fixes" I've read about, is something that's probably needed. The Fighter class isn't bad in itself, but the options presented need a severe overhaul, while the chassis of the class just needs to be upgraded slightly. Eighth's is another variant where there isn't one end all martial class, like Lord T's...
