From my tastings Im of the opinion that the Naga has way more flavour, yes its true... You do get to taste a wonderful delicate apricot type flavour from the Nagas.
The Trinidad Scorpions left a very sharp, taste reminding me of the 7Pot I ate a few weeks back from bents plants.
To go by taste to determine which is the hotter, is beyond my capabilities & your going to get various pods being hotter than others. As we all know both are as hot as hell & hang on to you for a long time, if one thing the scorpion hits you earlier than the Naga, I find the Naga a building burn that just hangs heavy & long.
I was not disappointed in the Scorpion at all, in fact it surprised me & I cant wait to try some more. Ill be growing both these types again without any hesitation.
