I believe JC would be the 2nd best by a very small margin (literally 1 int). Can pretty much do any of the standard 80 int bonus profs for your 2nd slot. Tailoring is unique by being a good deal better.
Your a human in real life I assume, you eat food. Maybe chicken, beef, veggies? You wear clothing too I hope.You have a job maybe, but I'm guessing you are not a farmer or seamstress. Pick you professions based on what you enjoy and what will make you gold. And if what you enjoy isn't tailoring or jcing or whatever you might find yourself needing.
