I have used erwin and Sparx Systems Enterprise Architect. 

The first time I used Visual Paradigm was when I was a university student. I didn't want to pay a lot of money and Visual Paradigm had a very good pricing model, so it meant that I could effectively pay for the level of sophistication that I was using at the time and dial it back down to a simpler version.

There are many products on the market, including some free versions. It really depends on the specific needs of the user. 

For example, if someone just needs to create UML diagrams, there are many free options available. But if someone needs a more comprehensive modeling tool for business process modeling, Visual Paradigm is a good option. There are also other paid tools available, such as IBM Glueux, Signavio and, and Elite, but Visual Paradigm is more affordable and flexible.

First, Visual Paradigm is more affordable. Second, it is more flexible and can be used by companies of all sizes. Third, it has a strong user community and a lot of training resources available.

I use SAP PowerDesigner in parallel with Visual Paradigm, and they have many similarities because their purpose is the same. 

Visual Paradigm is modern because of its UX, it gives a very good user experience, and has more models. For example, we can see many prepared models for modeling, but SAP PowerDesigner doesn't have some of these concepts. For example, you can document strategies in Visual Paradigm, but you cannot do it in PowerDesigner. We have a good user experience when we model with Visual Paradigm. The SAP PowerDesigner has more dated modeling tools.

An additional benefit of Visual Paradigm is the documenting engine. It has a very good documenting engine, which SAP PowerDesigner does not have. The documenting engine work by selecting your different models and text, and it generates the document for you. It maps it to a Word version, with all of your models, tables, and relations. It is a highly useful feature. One of our reasons for using Visual Paradigm is this document feature.

I have also worked with SAP Signavio and IBM Blueworks Live. In comparison, Visual Paradigm is very comprehensive since all the BPM and 2.0 modeling processes are available. Blueworks Live is not as complete when compared to Visual Paradigm, which is a very mature product. 

I had used Visual Paradigm before and insisted my current company to choose it.

At first, I was using just one solution, Visual Paradigm. I'm happy with it, but because Sparx Systems Enterprise Architect is a standard in my country, I also started using Sparx Systems Enterprise Architect. I prefer Visual Paradigm, though.

Regarding which solution is better, that would depend on your main project goal. If you're more oriented to modeling and modeling itself is most valuable to you, Sparx Systems Enterprise Architect is a bit better because you have better control of the models you create, so that's a plus. If you're into modeling for your programming project, I'd prefer Visual Paradigm over Sparx Systems Enterprise Architect. Visual Paradigm is best for programming-oriented architects rather than for enterprise architects.

In a previous organization, I had been using Visual Paradigm. I switched what I was using because I came to this organization and they are using ERwin. I did a little research into both the products for the sake of comparison and to see what the differences are and to gauge familiarity.  

We are also using process design software. I can't recall the name. It's a market leader visualizing for software. It's similar to Microsoft Visio, however, it is called something else.

Used Rational Rose and Systems Architect in the past. Moved to a new company where this was the standard.

I did not use a different solution before. I had no reason to switch to another tool due to lack of functionality.
