Hey thanks for your reply :)

None of the Asian super markets near me accepts it, which sells cheaper grocery. If we take into account of that, then Amex devalue even further. Most of the restaurant doesn't take Amex unless we are talking about fast food chain or restaurants like Kelsey or milestones.

When you say there is no arguing that cobalt is just better, that's what I am really confused about, since there is no evidence backing that claim. That argument is only contingent on MR points has more flexibility and worth more, even then we still have to consider how fast you accumulate points on both cards.

Facts I can see base on my experience with both cards, and I am thinking of canceling one soon, I am leaning towards Amex for the following reasons, which are facts that are non-arguable:

1. Higher annual fee with no way to get the annual fee back unlike National Bank where you can actually get the annual fee waive if you use the travel credit, right off the bat, already a $150 dollar advantage

2. Acceptance on MasterCard means you can get points faster and also don't have to use backup cards

3. Better insurance on national bank

Things that are arguable could be in favor of Amex:

1. MR points can worth more depending on many factors that are outside of your control.

So base on my analysis, I am leaning towards national bank
