> Nuclear with ion drive - even better (and the only choice beyond Mars) I'm sure you'll be interested in this concept. https://iopscience.iop.org/article/10.

  i'd say i hope for the hybrid - nuclear (especially fusion once we get to it) generates power while something like in your second link collects the mass for expelling from the drive (though not exactly "collects" - more like drives it through the electrostatic field, ie. using the tech like in your link in the role of the ion drive). The nuclear can work far beyond Solar system while the running out of the expelling mass is the main limiting factor here. If we can collect the mass along the way i think we can get to Alpha Centauri with 2-5% of "c" instead of 0.3-0.5% i mentioned in the other comment here (and we can accelerate to even higher speeds on the distances larger than the one to Alpha Centauri)
