I like CodeGnome's 1. Get certified, and 2. Get educated. This is key to every type of training and education, from formal universities and professional degrees to the trades to certificate programs, etc. We get educated because that is one of the necessary elements of growing our capability. The getting educated part is for you.
We get degrees, certificates, licenses so that others have some degree of confidence that you possess a capability. The certificate part is for others to evaluate you.
The predictive validity of both the education and the certificate / degree is never a guarantee and can range from zero to rather strong, depending on a lot of different factors. Where you get the education is one of the factors and can really drive your performance with real results or can really drive someone's biased assessment of your performance.
I do not really observe, in my limited experience, hiring managers worrying about where and how a candidate received his/her certificate but just that (s)he possesses one. That is not the case for degrees; there is a lot more bias with the schools from which one hails whether or not it really matters. So the answer to your question is what hiring managers are asking for in your geographical area and industry. Are they checking off the box that you have the certificate or are they digging deeper and asking how you got it?
Since you framed the question the way you did, I am assuming you do not really care about CodeGnome's #1, getting educated. If you did, then you would not have asked the question because you already have the right answer.
So, find out in your area what will get you noticed. My guess is, just get the certificate as cheaply and quickly as you can.
