Well, considering how both representations are actually built,
I would phrase it differently. You don't generate a parse tree
from an AST by adding to it, but rather, you create an AST by
removing ('abstracting away') things from the parse tree.

The way I read the question concerns more the API useful to developers
who want to hook up to the representation(s) coming out of the parser.
So, tools that only return an AST aren't suitable for tasks where
you need access to a low level representation, as some relevant information
may already be destroyed.
Ideally, the tool can generate multiple representations, and let users
control the processing pipeline, and only build the representation required
for a particular task.
