Worm Castings or Mushroom compost?

I was wondering everyones thoughts on Worm Castings vs Mushroom Compost? Is one better than the other?

Also while i have your attention what soil ratio does everyone use for an outdoor grow? I plan to use organic vegi soil mix (no added fertilizer), Perlite and an organic in a 30L fabric pot.

I consider compost as actual soil (when mixed with peat moss)where as earthworm casting is a nutrient additive I plan on blending earthworm casting with my natural organic fertilizer next grow

Both contain available nutrients although much more organic material in mushroom compost. Worm castings are fairly neutral PH but advise doing a slurry test of soil.
