I've worked with a competitor, Abakos, which is also a BPM tool, and I've found that the choice between cloud and on-premises deployment doesn't impact user experience significantly. For me, the advantages of ARIS Cloud are similar to any cloud-based solution - accessibility, cost-effectiveness, and receiving the latest versions.

There's another tool called Visual Paradigm. In a way, it's quite easy to use once you understand the product, but the lots of features and functionality information can be overwhelming. 

On the other hand, ARIS is more of a supported finished product, nicely packaged.

Prior to this solution, I used Enterprise Architect. The main difference between these two solutions is licensing. The modeling capability is similar, although with ARIS you have a clear methodology. With Enterprise Architect, you have to create more.

We have used other tools in the past. We have used the major software for example. We were not very happy about that solution because it was quite difficult to use for our users. Then we switched to another solution but I can't remember the name. It's a tool that is network-based. But it was a tool a bit like these, the problem was that for the corporation it was quite difficult because everybody made their own version of the description of the processes and then it was quite difficult to integrate everything.
