Is the 2.0 TSI / TFSI reliable?

It depends above all on the generation. The earliest units (2008-2012, without Valvelift) have more oil consumption complaints and somewhat more chain and tensioner wear; from 2012 the Valvelift design reduced oil consumption but kept carbon build-up on the intake valves as a weak point until, around 2016, supplementary indirect injection was added. The thermostat housing with the integrated water pump leaks coolant in several generations.^{[1][2][3][4][5]}

Is the 1.4 and 1.6 TU3/TU5 reliable?

The TU is one of PSA's most widely built petrol engines: more than 15.6 million units between 1986 and 2014. It is simple (no turbo, no direct injection or particulate filter, belt-driven timing) and has a reputation for durability. The faults owners cite most are cheap wear parts -ignition coils, sensors and thermostat- and not block failures or cylinder head design flaws.^[6][7][8][9]
