Sector 155 Noida Extension - Good Investment?

Hi all, I'm considering investing in Sector 155, Noida Extension. What's your take on the connectivity there? How's the metro access these days? Also, what about future appreciation? I’ve heard mixed reviews about waterlogging. Has anyone experienced that firsthand? Is it worth investing now, or should I wait? Any thoughts on the social infrastructure? Mujhe advice chahiye! Thanks!
