The verdict

These solve different shops. The F1 Ultra is a product-stand machine: two sources in one portable enclosure, so keychains, wood tags, and metal blanks all run through one small footprint at markets and in tight studios.

The B6’s MOPA source is the specialist play: pulse tuning for anneal blacks, color on stainless, and finish control a fixed-pulse fiber cannot reach. If metal is a sideline, the dual-source convenience wins; if metal is the business, buy the MOPA and never look back.
