Fastest and Reliable are two conflicting variables, and question cant be 
accurately answered without defining expectations for atleast one of them.
Big difference in distance between 99.9, 99.99 and 99.999%.
As well, if you use the DUO product lines, you can actually bond up to 4 
channels to increase the capacity by 4x, if channels are available and price 
is really no object.
Any frequency other than 6Ghz, you'd have to drop down to 99.9 reliabilty, 
and accept slower modulations.

Actually 18Ghz can do better than 11Ghz in some situations with low rain 
zone, because 18Ghz allows a bit wider channels and slightly higher power 
than 11Ghz.
But 18Ghz rain loss is still significantly worse.

The relevent question is whether its viable to put a half way point relay 
tower or not.  Two 14 miles links in series drastically increases your 
options, compared to just having one long 28 miles link, which pretty much 
restricts you to 6Ghz and the 6 ft minimum dish requirement.

But note that in your Greenville  rain zone, w/ 6ft dish and HC190 - 29Mhz 
channel, the DW tool still only shows 99.91% reliabilty.

This is why some have chosen to use expensive large channel Dual pol 5.8Ghz 
in remote environment that had the spectrum free.
