Top Soiless mix? Or to soil? That is the ?

im using perlite and #4 sunshine advanced mix .
Ratio of 7-3 . About out wanted to know whether all Soiless mixes are created equal or any u prefer and why?

Thanks for your time

I start all my plant's in soil and perlite,in 1 ltr pots,once they have got healthy leg's then i flip them over to coco and clay ball's 70/30.

Love coco has a medium since i have been using it ,i have found that the plants love it,but after about 7/12 days,the medium really only is a way of holding the plants in place all the feeding is done through the bottom tray (auto pot),via the root's,i never feed the medium(coco) after 7/12 days

But i still use canna coco a/b nutrients even while there in soil
