My Ender 3 was working AMAZING. I decided to buy it a Microswiss All-Metal Hotend. I called the company I bought the printer from, and they sent a technician to install it for me. Once he installed it and left, I started a print on it. The print quality was TERRIBLE. There was stringing everywhere, and the print quality was overall worse. I releveled the bed and tried tuning my slicer settings. I am using PrusaSlicer's default Ender 3 profile with just a few adjustments.
