With more depth on the character!!

I tend to gravitate to the more unique ones myself.

I'd love to see some unique adopts. They are the better in my opinion.

I tend to be more attracted to fursuit friendly designs~ the base can be either or.

Personally I think unique adopts make more sense because the character you're adopting will be yours, so it has to be something special~

I tend to favor adopts, but ones based on a singular set of lines or a collection of parts tend to get more money to work expended ratio.

Both have their allure.

Pros to the Base? A base means you can crank out multiple adopts of different coloring, species, and gender, but not have to invest as much time per adopt. You can also keep costs down if needed. Not to mention a base can make it easier to readily have a front and back image available, and/or expression slots, like with traditional reference sheets.
Cons? Things look similar, and you don't feel like you're getting the value from the adopt from a talented artist.

Pros to a unique character? Like the one I managed to snag from you, we get a character with a unique appearance that looks like it took a little effort to make, and feels custom as opposed to one off a base.
Cons? Aside from the effort you'd spend drawing the entire thing out, there's higher costs to consider, not to mention (from personal experiences in the past with these kind of bases), it's harder to make edits to a unique base for the buyer that wants edits made to their characters.

I'd say maybe look into investing time into both with your own unique art style, and then work your way forward from there. You don't need to commit entirely to one or the other.

I prefer bases cuz that provides many more options to make new characters rather than adopts

is this even a real question?
like do you think people would perfer a base adopt vs something that takes effort?

I make off base adopts normally, just figured I might be out of touch on what people want

off base is bea

base adopts are decent for those with a lower budget though since they can be made faster.
