Adult swim lessons

Looking for recommendations for local adult swim lessons and training. I just did my first session of masters swim classes at the YMCA and did not feel that it was a good fit for me. I was super slow compared to the other swimmers and was just feeling really discouraged. I received some tips from the coach, but had to do different workouts from the other swimmers. I did not know what to expect from these classes, but am wondering if 1:1 sessions would be more appropriate.

My background: I have done several sprint and olympic triathlons. Hoping to work on form and technique and improve my speed. I do not know how to do any stroke other than freestyle 😅

I've seen other posts mention swim423 and UTC being good options. Just wanting to reach out to see if anyone has any personal experiences!

Thank you!
