My experience seems to vastly differ from this. I love Strike and will continue to recommend them to everyone that can use them, because the UX ses great, they've resolved past issues, and Jack Mallers personally does support, fixing issues when he can.
I did have a hiccup before though. I've been using Strike for several years. 2-3 years ago, I had some issues with my bank account or debit card. I was trying to use a specific account to do deposits from. That was a joint account and had my wife's name on it. Plaid sucks. The account kept getting disabled and I'd have to reenable it often. Jack worked on one of my support issues as well about a year ago. Strike has been solid ever since.
Compare this to other platforms and it seems that Strike is light-years ahead of other offerings. No service is perfect and every service will have issues thanks to government regulations. Strike seems to be at the head of their class in that regard.
