Xapo are a private bank and so charge an annual fee, currently $1,000

As an early member, they are keeping my annual fee at $140 until 2027.

But they are a full bank with a 200,000 Euro bank guarantee.

They don't charge a fee on trades and use mid market prices.

Strike are a gateway, not a full bank, they are free to use but charge a trade fee and use spread prices.

As I have a Xapo bank account I use that mostly, but I also use Revolut and Strike for day to day stuff.
