That question is far too open ended to be answered.
CMW and CSW pots get a lot of crap for being only 2 or 3 times better than CLW but costing 6 or 15 times as much. And before you say Action Economy, barring something like getting a 100 stack of CSW pots at level 1, potions don't heal enough to be viable in combat. And since this isn't DDO and you aren't twinking your alt with 100k plat that doesn't happen.
There are a few > level 1 potions worth using, but they aren't very common, and most of the winners are things like Lesser Vigor, or Conviction, or Shield of Faith.
And then there are consumables that are not potions. Weapon capsules, alchemy items at low levels, stuff like that.
The biggest problem with consumables of the magical variety is that it uses a formula based pricing system when not all spells are created equal.
