[Unanswered]  Which Metal Fight Formats are Better (In your opinion)?

I've been contemplating about getting into the competitive scene for a while, specifically for Metal Fight since thats the gen Im more familiar with, and about 85% of my collection consists of Metal Fight Beys. So far there are 4 MFB formats I am aware of; Limited, Standard, 4D and Zero G. This is really the first time I've interacted with the Beyblade Community so I wanted to know, from you guy's experience, which format do you think is better in terms of accessability and enjoyment?

Also if this is the wrong sub forum to bring up this topic, I do apologize. I am new here and have not found time to get the lay of the land ^^'
