I only make that determination based on the individual filter. What applies to one part number filter will not on another, which makes blanket statements on this topic kind of useless.
For instance, I find that aftermarket oil filters for Nissan and Subarus, regardless of grade "silver, gold, platinum, etc.." tend to have a media can in them that is much smaller than the OEM filter. Even if the OEM filter uses fiber end caps, I'd rather have more media surface area in there than less.
The whole "micron rating" or "synthetic media" thing is all marketing hype to me. A full-flow filer like this is only going to do so much.
