Depends what you want out of your job. Alchemy will give you extra stats. I thought it was great.
Cooking and first aid are fine. First Aid, in my opinion, should be mandatory. Cooking, however, will not benefit you too too much; although you can restore yourself a little better between battles.
"Better"? All crafts are different, and cannot be considered better or worse. Tailoring you can make bags and cloth armor; not that a Druid uses cloth as often as leather, but the option is there. Still, I don't htink it's that great besides the 28 slot bags and the Belt of the Archmage...
Enchanting will make you rich. Near the end-game. You'll be ****-poor if this is your first character until then...
