the Pro PC17000 is faster,but why both price are equal?
which is better?
please help.

There are 3 components to memory:

Size
Frequency
Latency

You've given two (size and frequency). Without knowing the timings (latency), i can't tell you. Also haven't given the store you're looking at. If one newegg has one for one price and amazon the other, who knows, different businesses.

Lower timings is bettter. Higher is not. There are also other factors such as quality of heat spreader, compatibility, etc.

Pro I believe is their top Vengeance Memory. Vengeance of course falls below their top of the line Dominator and Dominator Platinum series.

which is better?
 
Truth be told, it matters little.
Faster ram is accompanied by higher latencies, negating much of the speed advantage.
Synthetic ram benchmarks can point out differences, but the difference in speed is hard to detect in actual app performance or fps.
Think 1-3% between the slowest and fastest.
With intel cpu's, speed matters little.
With amd cpu's it matters more.
Here is a good article on haswell ram scaling:

And... fancy heat spreaders are mostly marketing.
Ram vendors have found out that they can charge more for looks.
They are only useful to enthusiast overclockers seeking to find the fastest ram.
They actually hurt because they can interfere with some air coolers.
Buy low profile ram.
