Very suitable for any project where geographic data needs to be analysed or presented in a digestible format. There is more easy to use software for 3D and terrain work. For drilling data the plug in is limited and slightly clumsy in its execution although it is possible to draw the trace, snap to terrain and colour depending on geology, assay results, etc.
MapInfo Pro customer support has always been quick and very helpful with any issues I have had with the software. They usually get back to you about your enquiry within 24 hours and they also tend to follow up to make sure your issue was resolved. I find it refreshing to be able to contact their experts quickly and easily.
FME not only be able to do the data transfer and transformation, but also be able to perform the spatial process. Astera cannot do the spatial process at the moment.
QGIS works very well however I find it a little harder to use and find the tools/settings I need in QGIS. It has a lot of the same functionality as MapInfo however QGIS doesn't really offer a dedicated customer support form or service which makes it harder to learn the product.
