Haven't seen the food you mentioned or any moist foods specifically for bettas but IMO they do just fine on a decent quality flake, micropellet and frozen foods as a treat.
New Era pellets are the only ones I know to be a moist food and they are one of the best on the market IMO, was recently shown all the individual ingredients that go into their flakes and pellets (same ingredients, difference process to form flakes or pellets) and it was very interesting! New Era reps are the most interesting people to talk to and I learned many things in such a short space of time, especially as they are coming back for proper training session at a later date. But were talking about how oily their moist pellets are as it does look a little worrying but they point out that from all their individual ingredients, *all* oils are removed so that the oil they replace to bind the food is exactly the oils the fish need. Which is apparently *not* Omega 3 that lots of other companies include in their foods and promote because unless the fish live somewhere very cold and need to build up big fat reserves, they don't want omega 3 in their diet. That said... cant remember what the oil was that they use LOL. Random interesting information.
Seems they are working on ways to create much smaller versions of their pellets too which is fantastic news but it means modifying all the machinery used to make the pellets so they can be cut smaller! They have already reduced the size of the marine grazer block which was way too big for most peoples tanks which is a start..
To me, these foods look a bit like a rip off of New Era, the pots look similar, their descriptions of the foods are also very similar, even how they word it seems similar. To be fair, my loyalties tend to lie with whichever food that I find fish really like and the company that is not only willing to explain everything but really enthusiastic about it too. No good telling me their products are better than someone else's if they can't tell me why!
New Era and New Life Spectrum are both very good companies to deal with and when I have contacted them, they have been more than happy to discuss processes, what's in their foods, where their ingredients come from (I remember New Era stuff is generally all from the UK with a few bits from France at the furthest). Not that that helps for those not in the UK haha.

Would be interesting to see how the two foods compared if analysed.
