There's no such things as bis lists due to warforging and titanforging messing everything up.
Get familair with raidbots and simulation and use that to determin what gear is an upgrade or not. Guide to raidbots:

Theres also sources such as herodamage, the sim dumpposts by glynny, the spec guides and bloodmallet you can use to HELP you decide what gear to go for. You should still always sim your character as their values are based on their profiles and not your character so values might differ.
One final note, simc is incomplete right now. General cross class azerite powers are missing, a lot of trinkets aren't working and more. Check out these resources after launch again for better results than what they are now. Also the sim dump posts are based on prepatch and not bfa. They'll be updated soon.
Hope this helps you out more than a random link without context.
