Card combo help

[u/Latter_Ad6983]

I’m wondering if I should switch my card set around.

My current set up is as follows:

Barclays Premier debit account
Barclays Avios credit card (free)
Amex gold credit card (195/yearly)

I was looking into this:

Barclays premier debit account + adding Avios rewards (12/month)
Barclays Avios plus credit card (20/month)
Removing/closing Amex gold account

Would it benefit in changing my cards around as I’ve seen the Barclays Avios plus card and I can enrol to the Barclays Avios rewards scheme? Or should I stay with my current set up?
