When time permits, I'll run the routes on the Garmin on four different ways:
Truck - Shortest Route
Truck - Fastest Time
Car - Shortest Route
Car - Fastest Time
And then also run the route on Streets & Trips using Shortest, Fasted and Preferred. (Sometimes, especially if there is a significant mileage discrepancy between the load offer and what these routing options give, I'll then run it on PC Miler).
After the 4 Garmin options and then the Streets and Trips option, I'll end up with 3 or 4 distinctly different routings. The Garmin usually produces the most desirable route, but not always. Sometimes it's Streets and Trips. In those cases I'll use the S&T routing, either on my own or by forcing the Garmin to take that specific route.
I wouldn't want to rely solely on one or the other, that's for sure. But after having done plenty of routes on both the Garmin and Streets and Trips, I know for sure that over long term usage, the Garmin saves more time and miles than Streets & Trips does. Otherwise I'd be using Streets & Trips.
While driving, the Garmin wins hands down because it gives you precisely the information you need at a glance (where you are, next turn and when, and final ETA) without any unneccesary, distracting information as you find on the S&T screen. One touch of the screen gets you to other information on a couple on different screens, which is the same information that is generally displayed on the S&T screen all at once. All at once is nice, but it's more distracting just the same. You cannot take it all in at a glance, you must refocus, and zero in on the information you are looking for, and then process it.
On the other hand, before during and after a trip, when you need to use an Atlas to get an overview of things, maybe to figure out where you might go after delivery, whatever, Streets & Trips beats a paper Atlas up pretty bad, and a Garmin is beyond useless at an Atlas. Being able to zoom in, zoom out, move around, see what's close by, see the geographical overview of things, to use the map as a map, it was something I got used to, got comfortable with, got proficient with, and that's what I had the most dificulty with when I went from the laptop to a standlone. I'd be willing to bet that this is a large part of the reason people are reluctant to give it up, and so passionately (which is really funny, I gotta tell ya) defend its use, especially the ones who say they love the big screen. It's not the screen size as much as the fact you can do more on that screen at the once, and you can actually use the map as a map. Whether you're looking at a standalone or a laptop's big screen, whatever you're actually looking at is about the same size regardless, about 6 square inches. A laptop screen may have 110, 200, 255 or even more square inches, but I promise you, when you look at it, you're looking at just about 6 square inches (at arm's length). That's why the ones specifically designed for large vehicles, like an RV or a truck, tend to be large, because they are usually mounted further away, and thus require a larger screen in order to equate to 6 square inches at a distance. The screen size of these standalones is not by accident.
Audio feedback is pretty much the same either way, so making a case for S&T over a standalone because of audible spoken directions isn't much of an argument. Saying they are both a distraction isn't much of an argument, either, since we all know distracted driving is distracted driving. It's merely a case of which one has the
potential to be more or less distracting. The only argument that can be made is which one is
safer. People are gonna use whatever they feel comfortable with, whatever they prefer, but don't kid yourself into thinking that just because you prefer a laptop that it means the laptop is just as safe, or worse, safer, 'cause it's not. As a fellow driver sharing the roads with y'all, all I ask is that if you're going to use a laptop while driving that you keep it's risks in mind.
