sublingual roa is most optimal imo, so let's discuss the best tasting brands. these are all for the generic ir version:

teva - they don't taste 'good' but i kind of like the weird bitterness. along with the blue color it is kind of like candy. gives it some character, like coffees or ipas, you know. they break apart though, my bottle is full of blue dust.

granules - these are my gold standard imo. they dissolve the best, with a slight inoffensive chalky taste. i also like the oval shape tablet with the quadrant scoring the best.

alvogen - seems like they dissolve similar to the granules, but there is a strong neutral flavor that i find unpleasant. i'm not really sure how to describe it, maybe like plasticky with a hint of cornmeal. so far my least favorite tasting.

those are the three i've tried so far. what about you?
