I have dismissed bank debit cards for their inferior liability protections (e.g. Clark Howard 'Why You Should Never Use a Debit Card To Pay For Anything').
It was an easy decision for me. There were reasonable places to get acceptable interest rates on my cash, my credit card gave me 2% cash back on spending, and most of my excess savings was going into stock allocation that I could funnel into after-tax 401k contributions my prior employer's plan allowed. Times have changed.

I'm now in a very fortunate predicament of having excess cash to save (even after maxing out Series I Savings Bond contribution), but there just aren't any reasonable yielding options. I'm currently in a bank paying nothing, but offered a big bonus to open the account, and that will keep some of the money tied up for a few months. I've been eyeing First Foundation's Online Savings with 0.75% APY , which is relatively high but $75 on $10,000 there for a year leaves me yawning about whether it's worth my time to even go through application process if I'm going to wind up moving it again a few months down the road.
Now I'm being confronted with a B&M bank (FirstBank) with branches near me advertising a 3.0% APY on up to $25,000 for jumping through rewards checking hoops and using the bank account Debit Card for transactions *(see edit below). $300 on $10,000 is enough to get me scheming

If I spend $10,000 a year on my rewards credit card (which is a bit of a stretch for me) @ 2% that's $200, and if I open the simple High Yield savings @0.75% on $10,000 that's $75 for a total of: $275
If I have $10,000 in the 3% APY rewards checking, start using the debit card for my spending rather than credit card, I'll earn $300 just on that base deposit amount, and I'll like get it up closer to the $25k cap so it would be closer to a comparison of $750 to use a debit card relative to maybe half that if I'm using my rewards credit card and easy terms simple high-yield savings
Do Boglehead's have some input for me to consider on this?
I apologize if this deemed 'investing' and not 'personal finance', I was on the edge as to which sub to post in, but since this is a finance decision I'm personally considering this is where I posted it. Or is is it a 'personal consumer issue' with the banking services I choose


----- Edit to update:----
* Back with an update/correction about the specific First Bank "Performance Checking" account I was considering.
As I understand it now, it is NOT a typical "Rewards Checking Account" that make you jump through hoops to earn the special interest rate.
The 15 debit transactions + direct deposit is only the requirement to avoid the $11.95 monthly service fee, which re-colors my opinion of it a couple different ways:
- It's a separate consideration if I want to use a debit card to save $11.95 each month. Even if I potentially pay $143.40 in a year of monthly service charges, it would still net me a better interest rate then I can get elsewhere.

- With the interest rate not being a "rewards" benefit, I'm more skeptical that this is a teaser rate too good to be true, and won't last

We'll see how it goes.

Another edit:
If anyone looks at this, and is considering and in an area eligible to open an account at First Bank mentioned above, be aware that apparently they've added a promotion to do so with a $100 bonus if you open the account online with promo code: SWITCH2FB

Unfortunately I missed out on that
