Owner of Audio-Technica LP120X with Sumiko Rainier cartridge, got it in November 2023. Is it time to upgrade my stylus?

I recently (and finally got speaker stands) and have them nicely separated from the walls in my room. However, I noticed something with the sound. (and this appears with my headphones too) The bass is no longer as precise as when I got it and the low end kind of blends into each other if that makes sense. (I am not an expert with audio frequencies and things). Since it has been almost 3 years, and the stylus is interchangeable with nicer ones from the Oyster Series Sumiko cartridges, is it time to upgrade? Thinking about either the Olympia stylus or the Moonstone stylus. Only a 50 dollar difference from each other.
