Alternatives to Tableau?

I am a longtime Tableau user and instructor -- and I'm starting to get to the point where I've just had it with Tableau. It's become so complicated to get them to simply take my money and give me a license key (not to mention the outrageous price that can't be billed monthly) that I'm ready to depart.

What are you using as an alternative to Tableau? Which company is easier to deal with?
