I am not sure which is actually better. I have used both and have had issues with both. It would seem that built-in GPS in your vehicle (at least in mine) doesn't always give the best route where my phone tends to give the shortest route but doesn't account for traffic issues.
Test them side by side. Some cars use different technology to others but I would imagine most of them use map data from Google or Apple.
I prefer to keep my phones battery high so I always use the GPS in the car. Quite often I do not need it.
I noticed that this depends on the phone and the built in GPS of the car as well as the time of day. I tend to use both myself for this reason. Most cases, my phone is better for high traffic times, 4PM until 7PM and my GPS in my car is better for other times.

some good tips
Not many cars have a fancy navigation system in the dash, so you can either pick up a dedicated gadget to handle the chore or use that fancy smartphone you already own.
It is not just an assumption, yes, there are elegant and expensive four-wheel rides which are just as expensive as they are classy. These grades of vehicular beauties often have inbuilt GPS technology amongst other safety-related peripherals and features. Why else would it be all that expensive, I mean no one would want to lose their money in the form of a poorly secured car. But how about cars which do not come with this feature? We have to improvise with the available resources at hand, in this case, our smartphones will do the job just perfectly.
Today, most new cars have GPS systems pre-built into the center console– BlueTooth systems that allow drivers to stream music and access their phone hands free, and lane-keeping technologies that prevent drivers from veering outside the yellow paint. But the real question is exactly how often do you utilize your GPS system? Since smartphones have become a staple in our lives, many opt to use their mobile device to handle navigation
You can improve your chances for accuracy with smartphone mapping if you remember to download the area for off-line usage, but that may not be practical if you are a spontaneous traveler. If your smartphone storage is nearly full already, downloading a large number of maps can also become a problem. There was a time when real-time traffic information was better with dedicated GPS devices, but the gap has definitely closed, especially with crowdsourcing apps like Waze. The downside to Waze in remote areas is that unless there are other users on the same path, you won’t get any updated information.
