I have a 2014 1.4 TSI and I can't fault it.
I've had mine mapped so it's a got a bit more go in it than standard and it's plenty fast enough.
Fuel economy is decent if you drive with a bit of sense. Any long periods of acceleration will tank the mpg, get up to speed and keep it steady. Coming from a diesel that was the hardest part, my old civic I could just do as I pleased. But nonetheless, I still get 45MPG on my 16 mile commute, the missus' 2.0TDI only does 50ish on the same route.
Reliability, I've had mine since July 2019 and slapped a good 40k miles on it, currently sat at 73k
Only issues I've had is the blend door actuator failing and a blown turbo, which was self inflicted really.
I would say get one with MIB2, having something like CarPlay or AA is great if you do long journeys. The Seat Nav is rather awful and using a phone holder will break the vents if you have a heavy phone. Plus not mention MIB2 isn't plagued by cold weather issues.
