Noida Extension confusion -- should I even consider?

Noida Extension mein so many options, honestly I'm overwhelmed. My parents keep saying 'thoda dur hai, but ROI zyada hoga'. I'm looking at 2BHKs, budget around 60-70L. Heard mixed reviews about under-construction projects after so many RERA issues. Is it really worth the risk for potentially lower prices? The Antriksh Group has some projects there. Sector 33 looks more developed, but obviously more expensive. Ab samajh nahi aa raha. 2BHK vs 3BHK--which is better for rental yield if I decide to rent it out later? Has anyone else faced this confusion? Should I just stick to ready-to-move? Am I missing something?
