Best Credit Card?

[Speaks]

Man, I have to ask.
As someone that tries to never use credit cards. Why not pay yourself back?
I just feel like its a scam to use a CC for cash back or frequent miles whatever they are offering.
I will use the zero percent financing and pay it off in time.
Why not toss a hundred or two in some sort of high earning savings account?
Open an IRA?
Too many better options than making payments for "cashback".
Just my opinion here.

If you pay off balance in full every month you get the cash back and dont pay any interest.

Aside from my personal spending I put all my business travel expenses on a personal card and get reimbursed so I make sure I get the points / chash back. Its something like $100k a year in expenses so whatever rewards I get are more or less free money. I also have so many airline miles banked that my wife and I could fund 3 pairs of round trip tickets to Europe first class.
