Does John Innes compost really make a big difference in people's experience? I tend to look at the price, and go for a cheaper option like Arthur j bowers or murphys.
For tomatoes etc and annual bedding in containers I find a good MPC is fine.
For potting anything else I use loam based JI composts - sometimes I add extra grit for things like bay, rosemary, figs etc and other plants that need really free-draining soil. I use JI No 2 for growing on perennials etc and No 3 for shrubs, fruit trees etc that will be in the containers long term.
