It's quite simple: You should obey the rules and apply to the country that is the main destination of your trip. If that is Greece, apply to Greece.
And as o.m. says in his answer: It's more important that you address the issues that were raised in the rejection. There are a couple of questions here that might have some value, e.g.: Schengen Visa Refusal: Justification for the purpose and conditions of the intended stay was not reliable (which seems to be the same reason you got)

In your re-application, you must
I speak from my own re-application experience. See here for my story. I was eventually granted a new visa in my re-application for a second trip. I re-applied for a second trip with a different purpose and was eventually approved. It was not without considerable effort! I wrote a full cover to explain my prior denial in full transparency, attached details and excessive proofs for my next trip (hotel reservation, tickets to events, friends who I travel with and their info, etc.).
From my experience, you MUST be forthcoming with your prior rejection and you should know why your prior case was denied (if you don't, you must find out). It will be appreciate by the consulate if you proactively tell them and apologize and explain during your interview. If you try to hide, it will be really really bad.
For your case, since you got your first rejection back in oct 2018 I am assuming you are applying for a different trip with different purpose. So make sure you identify why you were rejected last time and deliberately explain the why and how you plan to improve this time. Re Greece, are you planning to go to Greece? Do you have sufficient proof that you are visiting Greece as a primary trip purpose? DO NOT APPLY via Greece just because it is easy! This is visa shopping!
I would agree that the reason "Justification for the purpose and conditions of intended stay was not provided The information submitted regarding the justification for the purpose and conditions of intended stay was not reliable" is probably the WORST out of all denial reasons; it shows that they just don't trust you. So you must gain back their trust by providing considerable more proof and evidence than a regular applicant.

You need a credible explanation why you are traveling to the Schengen area, how you pay for it, and why you would leave again. This is much more important than the question which Schengen country rejected you before. They all share one database.
