Questions about the t-jet engines

Wear me with the idea to buy a Punto or Bravo with 120 or 150hp. Is the 120hp approximately comparable to the 1.4TSI of VW ? Torque looks almost the same. Does the 150hp ? According to data sheet has not much more Nm, only more PS. How about the consumption, what do you need ? More GP or Bravo ? Are there reasons ? Thank you
