I need advice on which direction to go with my boys

I need advice on which direction to go with my boys I have two boys who stutter, ages 6 and 8. My 6 yo has stuttered since he learned to speak, and it doesn’t really get in the way of him getting his thoughts across. My 8 yo suddenly started stuttering when he was around 7. He has weeks where he will barely stutter, and then suddenly he will have weeks were he will stutter at every single word. This is one of those weeks. Sometimes it gets to the point where he gets frustrated and decides not to say anything at all. So now for the advice part. Those of you who stutter, did you do speech therapy as a child? I’ve read mixed things about speech therapy. We hadn’t done it because of insurance/tight budget but now we have both the insurance and the finances to pay for resources. Those of you who think speech helped, does the speech therapist you go to matter? Or are they all mostly the same? I just want him to not feel so discouraged while talking, and maybe get a little bit of fluency back. Thanks for your help!
