✅ Pros: Incredible value with Klipper and high speed.
❌ Cons: Large cooling fans are quite loud.
✅ Pros: Fastest open-frame printer; incredible CoreXY value.
❌ Cons: No enclosure; basic LCD screen.
The Neptune 4 Pro is the clear winner for budget value, providing excellent speed for half the price of the P1P. The P1P is the winner for users who want to be part of the superior Bambu ecosystem. **The downside:** The Neptune requires more manual leveling and maintenance. We really wish the P1P had the Neptune's excellent cooling system. Buy the Neptune if you love to mod, or the P1P if you just want to print.
