I pretty much always use tabs for getting on plane, solely to keep the bow from rising. My 25' boat has a big block and a Bravo 3, so it will plane out easily without them, even with a full load of people, but it has a stepped-hull and 24 degrees of deadrise, so there's quite a bit of bow rise without tabs, and it annoys me. With the tabs down, the boat stays level as it accelerates, like a ski boat.
My Bennett tabs are factory-installed and probably a little small, but they work great and I LOVE them. My acceleration routine: 1. Tabs down all the way, trim down all the way. 2. Throttle to 3/4 or so. 3. Immediately start trimming the drive up to open the exhaust and let the engine breathe (you can feel it gain power) while accelerating. 4. The boat gets to about 28 to 30 MPH quickly. 5. Bring the tabs all the way up. 6. Back off the throttle to 1/2 or so for my desired cruising speed. This process takes maybe 20 seconds. After that is all done, I then use the tabs to adjust listing or smooth the ride, as needed.
