High dumping factor, IMO, is useless as I never know will it help or not.
There are some amplifiers with 5000 - 6000 dumping factors which cannot handle difficult load.
On the contrary, high current delivery , is always, always useful and its difficult for me to imagine situation where high current delivery can hurt...
Also, when I say "high current delivery" I mean not over period of a few milliseconds as its only marketing.
Finally, high wattage does not mean that this amp is with high current delivery. Good example is bridged solid state amp e. g. Spectron stereo versus monoblock amp.
