FTR .25c warp drive would still be a game changer. At that point it is really more about fuel efficiency (the rocket equation sucks) and G-force reduction (less time spent speeding up and slowing down means a faster trip). It also has the benefits of not converting every hydrogen atom in the void into a micrometeor.
