ISU vs CU Boulder vs IU | ECE

Reposting here as this is the right forum.
Hi

I have an admit from the following universities so far :
Iowa state University Master's in Computer Engineering
CU boulder Master's in Computer Engineering
IU Bloomington Master's in Security Informatics

My interests lie more towards computer networks, security and IOT . I like the course structure at ISU and IU. ISU definitely has broader options wrt courses than IU. I heard that we can take cross-disciplinary courses from the Telecom program at CU Boulder and so had applied to the ECE dept. Now , I would like to seek help from seniors to understand which school might be better in terms of research, courses , TA/RA possibility and job opportunities in the field of computer networks..

Thanks in advance !
