What's easy? I've owned three 6700ks. All could run @5. The one I'm using now, I run at 5.0/4.6 for daily use, including gaming. Wouldn't want to do it on air. I've had one 7700. Did 5. In fact, did 5.2GHz. Wouldn't want to do it on air. Given the choice, I chose to keep my 6700 and sell the 7700. If you look at my benchmarks on this site, most, if not all were done with a 6700k @ 5.0 or 5.04.
They're basically the same chip. They score ~the same on benchmarks up to 5.0, with the 7700 always generating more heat. For Mr. Joe Average who wants to run @ 4.7 GHz, the 6700 is the better chip. It will run cooler with lower temp spiking at that speed.
After running benchmarks on and off for an hour, my current 6700k's hottest core idles @ 26C/1.075V with memory overclocked to 3200. The board temp is 24-25C. On the same system, I couldn't get the 7700k to idle below 33C no matter what I did.
The 7700 will go faster and may pull away doing some things in some software, but in everyday real-world use, the performance is identical, with the 6700k doing it all at lower temps.
Think of the 7700k as a hot, binned 6700k.
