This whole thread is talking about BeyondMeat burgers.
If you're comparing the healthiness of a premade vegan burger patty, you need to compare it to a premade (or equivalent homemmade) beef patty. You can't take salt out of the beef patty comparison and say "look it's better"
Edit: But you can compare it to actual products on shelves. The first frozen burger brand I can think of that would be a good comparison is frozen Bubba burger. If we compare the sodium content, Beyond patty is 3-4x higher in sodium. Beef wins! :) Although Beyond has half the fat.
