It has been some time since I have listened or read what counter missionaries have had to say but I am familar with some but not every counter missionary. Specific ones include Yisroel Blumenthal, Tovia Singer, Eli Cohen, Moshe Shulman, Tzvi Jacobson etc. I don't spend all my time listening to counter missionaries but I have looked at some of their material.
I need to get back into listening to some more if the Lord Wills.
I need to be very clear that if one desires to be an apologist, he needs to listen to the other side. But even then, we need to be grounded in the TANAKH and the NT so that we are not lead astray by falsehood and can hold onto the truth.
I am happy to learn from Jews and get a better understanding of what they believe rather than strawman what they were saying. Speaking even with Jews gets me thinking about what they are saying and to see if that fits with both scriptures
Let us pray that the Father preserves us through his Son via his Spirit. Let the Triune God preserve us forever.
