I have an 855 and a 3790LMT gps. I was checking the arrival time on both and they are off approx. 15 minutes while traveling. But when I arrive at my desination both arrival time was the same. Why? Both should be the same while traveling.

Well, the arrival time should be the same when you arrive at your destination.
As for the initial estimate, they could be off for a number of reasons. I'd suggest checking the route first to see if they are the same. One could be set to avoid highways, fastest/shortest route, eco-routing, etc....
Something else to consider is "my trends/traffic trends" and its effect on the routing.

Which unit is more accurate?
Forgot to ask, which is the more accurate unit? If one unit is accurate, try to see what is different with the settings on the other one.
Also, the inaccurate unit may need some time to adapt to your driving style. When I first used my GPS, it was up to 30 minutes off on the initial arrival estimate. After taking the route several times it was within 5 minutes.

3790 has nüRoute

The 3790 has the nüRoute feature whereas the 855 does not. If trafficTrends/myTrends were enabled on your trip, this could explain the difference in estimated arrival time.
Garmin claims that trafficTrends and myTrends predict your estimated time of arrival better.

EDIT: Also note the points that Shrifty made regarding your routing preferences and avoidances. And a hard reset will alter estimated arrivals since learned driving speeds are erased.

I have disable Traffic Trend. Cause too much problem. I will have to disable My Trend too. I will see what happens on my next trip next month.
