MXR Distortion + vs Boss DS-1 vs Proco Rat II

Which do you prefer? A comparison between what I call the first-generation true hard-clipping distortion pedals that came out in the 70s. Before then, there were only fuzz pedals. I’m using my Stratocaster plugged into my MXR Distortion , Boss DS-1, and Proco Rat II into my Fender Champion 600. Enjoy!
