Anime-wise, it's uncertain since Sarada has Sharingan, with which she's shown enough proficiency to copy Boruto's shadow clone jutsu while only having 1T. She's also an accomplished marksman whose skill is already comparably Jonin-level. Her Taijutsu is still unexplored, however she scored highly in the physical assessment, coming at #3 place if my memory serves my correctly, implying she's already formidable enough to match Boruto/Iwabe physically - and this is not throwing in her CES with which she took out 20 Shin clones.
Taking all of the aforementioned into account and the fact she has a Fuma Shuriken she can probably manipulate to the same extent as Part 1 Sasuke, I'd say Sarada could give Boruto a run for his money. But, I'm not saying she'd win. But it could go either way.
Manga-wise, Boruto has showed a more versatile skill-set and has far more dilated development. So Boruto is obviously stronger. But this doesn't mean Sarada would certainly lose. It just means Boruto displays the capability to win.
