The key difference between both of the software is the amount or capacity of the tool to check the duplicate contents. You can check less amount of material at one time in the free version and more in the purchased version.
In the free version of the provided software you get size limit of the work to be checked, and maybe you have to face particular wait time to check another article. This thing does not make any tool unreliable and unworthy to use. It can create some problems for those people who want to check work in bulk, but due to size and time limitation, they can do so. Therefore they go for the purchased version.
