Is it worth going to PEC Chandigarh taking into account that its ranking is deteriorating?

PEC Chandigarh was ranking at 39th before but now it is at 68th rank. It is often argued that NIRF ranking is not legit. 

For instance - DTU is placed so low and VIT is placed above BITS this cannot be digested as BITS is way better than VIT in every aspect. Till IITs, it can be digested but after that, it's a joke. 

The public perception of PEC is impressive. Thapar University is placed higher than PEC but PEC is way better than Thapar in every aspect. 

As a B.Tech student, the main focus will be on placements, so below given is some placement stats of PEC: 

Private colleges are better than NIT and PEC. NIRF also takes into account the campus, Ph.D., publications, Research, etc. Maybe PEC is lower in that but if they consider only B. Tech then it will be placed much higher.
