I'd go with the Octavia, brilliant car, never go wrong on you and with a £500 Jabba remap you'll outrun any hothatch, they produce so much torque it's not even funny
It was going so well until then....
As with any car there is the possibility that things may go wrong (the rear window for example jammed on my old Octy vRS - fixed under warranty but still its something that can go wrong).
How are we defining outrunning a hot hatch? In a straight line even a remapped vRS will struggle to pull more than a couple car lengths on a Megane R26 / 225 Cup, Trophy. Point to point (B road blast) a Megane R26 will still be quicker (the vRS understeers when pushed hard, rolls too much (in comparison to the Megane) and won't be able to get the power down out of the corners as quickly (again in comparison to the LSD equipped Megane). The vRS is good just not as good as some of the competition in some areas.
Of course everything is relative, an octy vRS is still an excellent car (I used to own one so this is more than just a review based opinion) but it really does depend what the op wants. The Meganes for example are better drivers cars (R26 especially) yet lack the practicality of the vRS so its swings and roundabouts.
