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 / 1.6 16v E-TEC II reliable?

The 1.4 and 1.6 16v GM Daewoo E-TEC II (first-generation Lacetti/Optra and Aveo) have a timing belt and, according to the Polish press, a moderate fault record. Documented issues are faulty valves in the first units (2004-2005), lambda sensor faults and a few cases of oil leaks or oil consumption.^[6][7][8]
