Looking to replace our EA tool (Currently using Sparx). Anyone have recommendations/personal experiences working with the vendors in the Leader corner of the Magic Quadrant they can share (especially these vendors: Orbus (iServer), LeanIX, BizzDesign, BOC (ADOIT, ADONIS), Avolution (Abacus), Ardoq)?  We require support for the TOGAF framework, Archimate/BPMN/UML modeling languages, ARB approval workflow as a starting point.

Our organization uses LeanIX, what I like about this tool having used it for over a year, is it's quick to onboard and gives out-of-the-box integrations to multiple Enterprise tools like Atlassian, ServiceNow, and such. 

We looked into multiple products, Abacus is quite complex and need long learning curve. There is new version coming from ServiceNow covering EA part (replacing Application Portfolio) it looks very processing if your using full SNOW platform. Otherwise I recommend simple easy to use, currently we are suing Mavim (uses visio as input)  and later on moving toward SNOW.

We are implementing Ardoq at the moment. It supports TOGAF, ArchiMate and BPMN. Even at the early stages of the implementation our stakeholders are thrilled with the access to information and the real-time nature of the reports and visualizations. Their Presentations will be a crucial tool for us to communicate with governance for portfolio management, app rat, ALM and BC management. 

In the past I used System Architect, iServer, Erwin EA Agile, and iteraplan. So far, this system makes metamodel updates, reporting, and visualizing data so much easier.
