Am I still getting a good deal with AT&T postpaid?

I have 7 lines on a shared plan. I have it through a discounted rate AT&T offers for their unlimited plans (25% for military, teachers, healthcare workers, and first responders).

It comes out to $31.30 per line after taxes, for the first 6 lines, on AT&T’s mid-tier plan (50GB premium data and 15GB hotspot), and the 7th line is on the top-tier plan at $37 after taxes, in order to retain their HBO Max benefit.

Total cost for plan = $225 for 7 lines

Also, we trade in our phones every 3 years now to take advantage of AT&T’s iPhone trade in promotions which give $1,000 off the new iPhones. So in essence we get 7 brand new iPhone Pros/Pro Maxes for free every 3 years. Obviously this locks you in for a 3 year billing period to get the full credits but to me it seems like I’m getting a great deal when everything is considered.

So to get to my question. We are about to upgrade our phones to the new iPhone 16 Pros that come out next week and I was wondering if anyone here can suggest a better deal/plan than this before I’m locked in with AT&T for another 3 years.
