ArcGIS

Quality and features. There aren't any other softwares out there that have the capacity to map and render with detail.

Very slow in terms of processing as compared to QGIS. Efficiency could be better. For now it gets the job done.

Just like any product, you need to take time to learn how to use it but it’s one of the best products I’ve ever used.

In between jobs, I wasn’t using this product so when I starting using again there was a big upgrade so I almost had to relearn how to use it.

Built using standards such as COM, XML, and SQL, ArcGIS can be easily integrated with the structure of the information system and data of any organization or individual. Given that GIS extends to new applications and new user communities, ArcGIS also solves the challenges of offering and receiving data and related GIS services to users around the world. The versatility and easy to use allows ArcGIS to be used in a variety of areas: from land cadastre, geodesy, cartography, geography, and telecommunications, to geology, ecology, management of water resources and subsoil, oil and gas industry, and even remote sensing. Its technology of Geodatabase allows you to effectively store heterogeneous data and easily use them in complex projects and systems. In the geodatabase, users can define rules and relationships within the repository that define the behavior of spatially interconnected geographic (or geological) objects and object classes and ensure data integrity. With the help of ArcGIS it is possible to prepare qualitative cartographic products with all necessary elements of marginal design. Also, you can quickly create a realistic virtual 3D scene based on spatial data, using digital terrain models. With a lot of possibilities for processing of both raster and vector data, and its strong functions for map algebra, editing, and spatial analysis, together with the latest data models and control make the ArcGIS family of software products ones of the leaders among GIS software.

I have been using ArcGIS for almost 10 years and I can testify that this software is difficult to study, a very complex program for a simple user, the program is only for those who take the professional level, so, to exploit the full potential of ArcGIS (for example processing of multispectral and hyperspectral images, geostatistical studies and so on) you need to dedicate time, endless hours of study. Other con that I see, is the high price taking into account the purchase of any additional modules, it is a very expensive program, but, once and again, the potential is almost limitless once you get to dominate all its functionalities.
