It is tagged as DAI, so that's fine. When i comes to best in terms of gameplay, I dunno. The powerful but short-lived self-buffs from Tempest are not my cup of tea. Assassin is easy to use, but a bit dull, to be honest, and Hidden Blades breakes my immersion badly. How is someone able to pull this off without magic? My vote goes to Artificer. Useful party support, nice colourful explosive balls and some crazy yet effective build options. Did I mention the exploding balls?
