It might help if you define what a “better school” is for you. Do you mean better in a specific major of interest to you? Or different enrollment size, different city, frats or no frats, weather, various rankings of colleges?
If it is predominantly ranking driving your desire to transfer, Forbes Best Colleges list has UMD at 63 and CWRU at 100, so it appears you are already at the higher ranked university of the two. Fiske’s Guide To Colleges (referenced in this thread) recognizes UMDs academic quality at 4.5 and CWRU at 4.0, which indicates you are already at the better academic option between the two. The list at Washington Monthly has CWRU at 132 and UMD at 50.
There are many sites/services that rank colleges and if ranking matters to you, you should make sure you include as many ranking opinions as possible to help you make a more informed decision. Also, you should review the methodology of each site to ensure the factors important to the reviewers at any individual site/service in ranking universities aligns with the factors you consider important in choosing a college.
