Taste is subjective, as we all know, but from my experience most companies have some flavors they do really well and others they dont. Right now I love most of Flavor arts offerings. TFA has some I can't live without and some I can't stand. Same with Flavor West. Flavorah has some that look very promising as well and I made a huge sample order with them to see what I like and what I dont. My advice would be to look for reviews of the flavors online then buy some small samples of the ones you are interested in. Start with low percentages in your initial mix and work up from there. Also, steeping time is a huge part of flavors coming forward in a mix. Some taste terrible right away but taste amazing after a week of steeping. Trial and error, lots of it, and eventually you'll find some that you love.
