Quick verdict
X1 Pro is compelling for a compact 3-in-1 workflow and lower entry price. MetalFab is compelling when you want the xTool ecosystem, published 800W/1200W material tables and a broader fabrication platform.
Functions and positioning
XLaserlab emphasizes welding, cleaning and built-in cutting. MetalFab’s exact cutting capability depends on package/configuration; do not assume the base welder package includes the full CNC cutting platform.
Before you decide
Compare full-package price, electrical requirements, service, return terms, actual material/thickness requirements and whether cutting is central or incidental to the purchase.
