I am mainly interested in condensed matter theory/other theory oriented sciences. I did not do much research during undergrad (something that I regret

What is the general reputation of Purdue and Georgia Tech (and some particular information in theoretical fields, if possible?) I believe that Georgia Tech has a stronger CME department, but it also does good research in Gravitational waves, etc. What are your views on these places, and which might be more suited to my interests?
Thank you for your help!
