New Mohali builds are a quality nightmare

Mohali construction quality is a huge concern. I'm in a 2BHK in Sector 69, thinking of upgrading to a 3BHK or villa. Visited Mapsko Gardenia, and the visible quality is worrying. Hearing about minor cracks, shoddy finishing, and seepage after just a year from residents. I already have a home loan, so this premium price jump needs serious justification. Are builders just cutting corners? Why pay so much to fix basic issues post-possession? My current older place feels more solid, honestly. I'm dreading snag lists. Anyone else faced this with newer Mohali projects? Does a 'reputed' builder guarantee better construction, or is it just marketing? Need real recommendations.
