lift help, plate bumper winch

As the title says, I could use some help from the experts on this.
my question is how is using a spacer any different then adjusting the 5100 up? Im currently running 5100's and eibachs, 5100's set at .85 putting me at 2.45" of lift but im weighed down with plate bumper/winch. Wheel measurement is 21.75" driver side and 22" passenger. So thats only about 1.5" of lift after the weight. I want another 3/4" of lift give or take. What would work best, a spacer or 5100's up another notch? Toytec makes a spacer that gives ya 3/4" of lift but how would that be much different than adjusting the 5100's up a click. If it makes any differnce its not a mall crawler build but im sure there are some people that off road harder then I do. Thanks for the help, I looked around and couldnt find an answer to this particular problem.
