I'd say utility but for the most part, every alt out there is just some sort of copy of Bitcoin or other existing alts but I guess if it was for the long term then utility would 100% be better compared to something like hype lol. At the very least it introduces the idea that the coin would have future progress or development which could lead to potential positive market movements of the coin.

And I'd say memecoins are a better topic on online forums. Why? Bots lol. Plus, short term topics are more likely to be more apparent in forums since they would naturally pop up every now and then, compared to a project with "potential".
