Best trust jurisdiction?

Not the answer you're looking for, but choice of jurisdiction should be made in consideration of the location of risks. I.e., what and where are the threats you're protecting assets from? What assets?

Broadly speaking, the most popular and tested jurisdictions are Isle of Man, Cook Islands, Nevis, Samoa, Gibraltar, BVI, and Cayman Islands. But there's no silver bullet that works in every case.

On what basis have you decided that a trust is the right vehicle for you? Was it a suggestion by a lawyer who understands asset protection?
