The price is higher than my usual powdered food. The bags are not convenient (they are difficult to close properly, it's difficult to make a bag stand on a table, and it's also difficult to quickly distinguish the top of the bag from the bottom). The texture is OK (rather liquid) but it's hard to shake it properly so as not to find some bits of powder that are not dissolved. The flavors that I tryed are globally OK.
As for Wundrbars, they are convenient and the texture is alright. The chocolate-hazelnut flavor is good, but the chocolate vanilla flavor not so much. After tasting the chocolate-vanilla bars, neither me nor my girlfriend like it and don't really want to eat some again.
