The BLACKI preference and IIM tag hold true for the 2 year MBA via CAT. I believe SPJIMR holds a definite edge as compared to L,K,I in the 1 year MBA given that it is much older and hence a better alumni network. The location advantage of SPJIMR is also considerable given the fast paced nature of 1 year MBA. I believe that it is probably the 5th best option after IIM A,B, C and ISB.I agree with this, I was browsing through the profiles of the SPJIMR PGPM graduates on LinkedIn. I have browsed through at least a 100 profiles for each of SPJIMR PGPM and one year IIMs. Except for IIM ABC/ISB , I found SPJIMR folks in a better position than the IPMX/EPGPs of IIM L,I,K.
You can check this and verify for yourselves.
