It's a difficult subject to get one's head around as peat-based compost is not environmentally friendly but what are the alternatives, how well do they work and what do you have to look out for when using them i.e. more watering, price of course, but then you shouldn't stint on that as it's a waste of precious growing time if you buy el cheapo stuff. I think it's best to avoid the latest newby until it's been properly evaluated over time. I just get Jack's Magic which does the job (so far) and am not going to try out anything new at the moment until I know more info on performances etc.
