In my opinion, better opt for HWH Raj. Second priority should be SDAH Drnt and followed by SDAH Raj. I gave this judgement based on over all comfort, cleanliness and food quality. HWH Raj is top most priority because it always runs on time. In SDAH Raj, we received couple of complaints regarding poor food quality and cleanliness. SDAH Drnt started maintaining its timeline after change in its TT.
