New to TOAD for SQL Server, seeking advice

Hello. We are ramping up an evaluation period for migrating Oracle databases to SQL Server. We are big time TOAD users for Oracle, and I have a group of non-admin power users who will definitely need a tool for a front end.

When I look at what is available for me to evaluate, it’s overwhelming! I also notice that the trial version is for 30 days, which definitely will not be enough time. I

I’d appreciate some insight into what product I should be looking at, and experiences from Oracle to SQL Server that might help.

We are using SQL Server 2016 for this project.
