Upgrade tiers first or craft items?
It seems like crafting is better because it gives you points for the concierge that will get you large chunks of crafting materials you can then use to upgrade.

I ended up doing the same. You need far fewer craft items per craftable versus what you need to level up once, so get the crafting out of the way first then start banking to level up. It seems to me that I am accumulating mats for crafting faster than I thought I would, given the daily challenges, what my gamblers drop and the mats accumulated from Moe's. I'm not expecting to be at level two by this afternoon or anything. It will be a long slog, but better to focus on that after making what you can.
