✅ Pros: Incredible value with Klipper and high speed.
❌ Cons: Large cooling fans are quite loud.
✅ Pros: Professional enclosed printing at a mid-range price.
❌ Cons: Basic screen and slower camera than X1-C.
The P1S is the superior winner for advanced materials and software reliability. The Neptune 4 Pro is the king of budget value for large PLA prints. **The downside:** The Neptune is very loud and requires more manual maintenance. We really wish the P1S had the Neptune's excellent nozzle-cooling fans. Choose the P1S for a 'set-it-and-forget-it' experience, or the Neptune on a budget.
