Comparing fictional faster-than-light systems cautiously

Which science-fiction form of faster-than-light travel seems most realistic?

Warp, hyperdrive, and wormhole ideas have theoretical analogues, but none is presented as settled or certain physics.

The answer begins by acknowledging that theoretical physics lies outside the stated area of expertise. Warp-like ideas are being explored but may not work as Star Trek depicts them. Hyperdrive also appears theoretically interesting, while Stargate's wormhole drive is the fastest fictional example and resembles a concept that might have a real analogue. The answer remains deliberately tentative and separates dramatic usefulness from a confident prediction about future propulsion.
