Dridha Elite ya Hark Sai? Samajh nahi aa raha!

Since January I've been checking out Dridha Elite and Hark Sai Group. Hark Sai is cheaper, obviously. But is it worth the risk? Dridha seems safer in terms of builder reputation. My parents keep saying 'sasta roye baar baar'. Change my mind? Which one for long-term appreciation, guys?
