Beyond Compare is extremely good at the task of comparisons, whether that is text file comparisons or folder comparisons. It does a great job of easily highlighting the differences for users, and giving them the option of merging (in the case of text files) or synchronizing (in the case of folders.) In either case, no one on my team has ever had any reason to reach for another different tool.
IBM Rational ClearCase might be better suited for a smaller / simpler code base. Larger code bases really slow it down... but then again there are better alternatives out there for source control
Rational ClearCase is excellent for handling versioning and branching. No other tool I've used has the depth that ClearCase has when it comes to handling complex branching scenarios and identifying where certain versions of particular files are within a particular configuration.
Rational ClearCase handles parallel development of many dependent applications really well.
The use of ClearCase Views to switch between projects and configurations is extremely convenient as opposed to the local workstation model of the competitors.
For date formatting discrepancies the software does not automatically mark the dates as equivalent; for instance ‘2019/10/15’ vs. ‘15-OCT-2019’. This would be considered a difference.
The columns/report must be ordered similarly. If extra data is available in one file, it should be removed or extra rows will be marked as differences.
For spreadsheet comparison, the user must save the file on the proper tab and then “recompare” within the tool. There is no way to switch between sheets in the software.
Again, given the intuitive nature of this program, there is barely any learning curve needed. It is simple, reliable, accurate, and just one of those tools you always have with you and rarely think about until you don't have it. Then it is a case of OMG what was I thinking? This program is just very easy to use, and that makes it more valuable to me than some of my other software tools that cost significantly more.
I have never needed support for this product other than learning how to use a new feature I was not familiar with. User forums and user groups that have used this product for their own purposes have always sufficed for anything that I needed help using with the product. Some of the features could be a little better outlined, but overall very easy to use.
We've tried many: Code Compare, Meld, UltraCompare, and WinMerge. None of them have the depth of features and speed to handle the work we throw at Beyond Compare. The multi-tabbed interface allows us to sync multiple servers at the same time. It understands multiple file types, metadata, and encodings. It's the best tool for the job.
If development is centrallized to one location and your company releases hundreds of customized versions of your software per year, then ClearCase is the best tool for managing the complexity of multiple versions of customized software. If your company has globally distributed development, then I'd recommend Team Foundation Server over ClearCase. If your organization uses Agile Methodologies, then I'd recommend TFS with GIT.
