This, if you’re worried about acceptance abroad then those are the best. Discover gives great lines of credit for subpar scores but acceptance isn’t as wide as visa/master. You can forget about Amex abroad as well unless you are staying in a g20 country.
We like our Sapphire preferred since we have a line of $20k with them and the perks are great but you said you can’t bank with Chase. Our quicksilver cards are “ok” but the lines are on the lower end between $5-7k and all they give is cashback, the wife’s venture card is shyt and we’ve been looking to cancel that one out for a while.
Ive been debating leaving AMEX and getting the Chase Joint since its comparable in many areas but Ive been with Amex close to a decade so idk
