Which Rifter 1.5 or 1.6?

Hi friends, I have been a Peugeot partner user for 6 years, but I want to sell my car, which is at 60,000 km, and buy an automatic gear rifter, do you think 1.5 or 1.6 or do you have any other ideas? I am waiting for your answers. Many thanks in advance to all of you.

Greetings, both are considered the same in terms of engine structure. 1.5 can be preferred because it is a more up-to-date engine.
