Pros & Cons
Longer Orange 4K V2
+Better light uniformity than the V1 means fewer dark patches at plate edges
+WiFi at $199 is a feature the original didn't have
+Compact enough to store in a drawer when not printing
−4K resolution is dated: the Elegoo Mars 4 offers 7K for $149 with better community support
−120x68mm plate is small even by entry-level standards
−Longer's support community is thin: problems are harder to solve than on Elegoo hardware
QIDI X-Smart 3
+Fully enclosed CoreXY in a footprint smaller than most open-frame printers
+35C chamber heating helps layer adhesion on ABS and PETG without a full 60C setup
+QIDI's slicer is better than Creality's for enclosed use cases
+600mm/s speed in a machine this small is impressive
−175mm cube is the real ceiling: anything larger needs to be split and assembled
−QIDI's community is a fraction of Bambu's or Creality's size
−35C chamber heating is modest: the X-Plus 3's 60C chamber is meaningfully better for engineering materials
