It's hard to imagine how Tom Holland's Spider-Man could be "even cooler," especially if he's divorced from the Marvel Cinematic Universe. But it's not like Sony has nothing going on, and that seems to be part of why they don't want to give Disney a 50/50 split. They have enough going on through their own merits at the moment, thanks to the success of Venom, and Spider-Man: Into the Spider-Verse, not to mention the two shared movies with Marvel Studios, Spider-Man: Homecoming and Far From Home. The latter recently became Sony's highest-grossing movie of all time.
