Having friends studying in both the institutes, I can assure you that among them Panjab University (PU) is better. CGC Landran is apparently a private institute mainly affiliated to PTU.

• Panjab University (PU) shares a boundary in a better location, as opposed to CGC Landran. PU has earned more value than CGC in every possible way.
• For all purposes, you should first try for PU, if you do not get admission, then try for PU affiliated colleges.
• Unfortunately, if these affiliated colleges are also not in reach, then they try reserving a seat in CGC Landran.
• CGC Landran has limited seats as well, but it is comparatively easier to get admitted there than it is in PU.

Now, considering various factors, both of them are compared below in a brief way,

Thus, considering everything, it is suggested you go for PU rather than CGC Landran.
