As one of my civil-trained helicopter instructor friends pointed out - you're coming from a situation where you're never, ever close to any limits on engines or transmissions in your close-to-sea level, relatively light weight aircraft. You also have plenty of time to prepare (some might say over-prepare) your missions. And the UH-60 has a sophisticated (in the true Greek meaning) AFCS, which almost no light civil helicopter has.
In the civil world, things are much different - much closer to limits in power and performance all the time, and often not much time to prepare for a mission. Also, civil performance charts are nearly useless in comparison to military perf charts, so you're not helped there.
Get some R-22/R-44 time and you'll have your eyes opened.
