I'm equally indecisive. If I were looking at a +1 offset, I'd look at the Fuel Sledge. That was the wheel I really wanted but didn't come in a +20. Of the two you posted I probably prefer the Fuel. I think the Method looks a little cheap IMHO.
I'd want to see a 0 offset with a 305. From a +18 you're picking up about 0.75" on the offset plus more on your tire. That may be too much for my taste.
I posted a profile shot of the +20 with a 295 in my thread so you can see how it looks.
Personally I'd go option 3. I think a 34 on an 18 inch rim looks great, and I love the Nittos. My least favorite of your options is #2 because I don't care for the look of a 33" tire on a 20" rim. I think 20s need 35s.
