All of the tools have 4-inch dust ports for use with a dust collector. Some shavings will come out of the top or side of the jointers, but airborne sawdust is completely brought under control for all of these tools with the use of a competent dust collector. When jointing without dust collection, the dust ports have to be removed to keep the gravity-fed discharge chutes from clogging. Shavings flying out of the tool by the cutter head means a clog. With the machine off, reach all the way up the chute with a yardstick or scrap of wood to dislodge the shavings up inside the body of the tool. Only use wood for this, not anything metal, because your probe will likely contact the exposed knives on the bottom of the cutter head.
The built-in mobile base on the Grizzly is a great feature that every other manufacturer has overlooked. The ability to easily move a 257-pound tool around the shop or job site unaided is very useful, and saves unnecessary stress on the jointer's bed and ways that happens when it is lifted by the end of its tables. Even if the machine never leaves your shop, there will be times when you have to move it to the center of the room to handle extra-long boards or even to clean or rearrange the shop. When the swivelling caster is disengaged, two levelling feet on the same end of the cabinet can be adjusted to stabilize the machine.
The Craftsman's fence design was less substantial and therefore less stable than the rest. The short fence support bracket, loose-fitting keyway, and odd cam-locking lever all added to its shortcomings.
