Ketostix urine strips or blood ketone meter?

Hi, all! I'm resupplying all my meds. I was about to renew my ketostix, but then I saw a post showing a blood ketone meter. Curious if I should invest in a blood ketone meter or stick with the stix?

(From my googling, sounds like blood meter is much more accurate but will cost more. If it's the smarter thing to do, I'll get the meter. Just trying not to set money on fire.)
