The Cobra model PR3850-2 WX EVP that I have is an older version of the model you are looking at currently and my Midland GXT710VP9 is also in the same family.
I have compared both of them next to one another and in no range tests did the Midland do as well as the Cobra. Both the receiver and the transmitter are better in the Cobra model.
The 5 watt rating on the Midland is misunderstood as the manufacture in my opinion wants the reader to think that the unit has a 5 watt transmitter when in fact the words on the packaging is “5 Watt Range Performance”
My Cobra does has a higher measured R.F. output power on 3 different meters over that of the Midland. The Cobra also has a signal strength meter that feature is not on the Midland unit.
Aside from some cosmetic (mechanical) differences that would be subjective to the user, the Cobra does the communicating function much better with every test I did having both units at the same locations and with comparisons done with high powered base GMRS units to the hand held units under test.
Both of my Cobra and both Midland units under testing performed essentially the same within the same brand.
Your mileage may very.
