Oh yes, the vacuum sealer is WAY better at stopping freezer burn.
Also, you don't have to use Foodsaver brand bags. There are other "Foodsaver compatible" bags available.

Reynolds came out with the first battery powered hand held food vacuum that was able to draw out most all the air from their provided bags. Foodsaver and others followed suit and made their own versions. Ziplock's hand held pump was fail, but I still buy their vacuum bags to use with my Reynolds EZ-Vac.
Ziplock tried to make it impossible to use their brand bags with Reynolds Ez-Vac, but all one has to do is to hold the Ez-Vac's suction cup a little off to the side of Ziplock's circular suction entry point. Simple as that.
Tip for those "re-using" these types of prefabbed bags: If the bag leaks after re-sealing them (and the bag hasn't been punctured during vacuuming), rub a drop of vegetable oil over the seal strip. It will reseal that area.
