What is the best interpretation to be made from Simulate max stress prediction?

[JS_9824412]

Good morning, I ran stress analysis on 3 design options with 3 different convergence methods. The maximum stress results are shown in the diagram above. How to interpret it?

1: Design-3 is the best? 

2: Never trust Quick-Check (QC) and Single-Pass Adaptive (SPA)?

3: Always run Multi-Pass Adaptive (MPA)?

Thanks.

Design-2 is the best if using the data from SPA. Design-2 is the worst if using the data from QC.
