Best use cases

Choose the Ryobi RY909500 if you want 8000 running watts for home backup or heavy tool use, but you care more about moving it around than stretching runtime. At 198 lb, it is a bit easier to maneuver than the Firman, which can matter if you are rolling it in and out of a garage frequently or loading it for occasional job site use. It also provides 9500 starting watts, which is typically enough for many common starts like a refrigerator, sump pump, or smaller well pump, as long as you manage loads and avoid stacking too many motor starts at once. The tradeoff is noise and refueling frequency, with an 85 dB rating and about 7.5 hours at 50% load, so it is less pleasant for overnight use near neighbors.

Choose the Firman P08008 if your priority is a more livable backup experience during longer outages. The 74 dB rating is a meaningful step down in perceived loudness, and the 12-hour runtime at 50% load is a big advantage for overnight operation and fewer fuel runs. It also has 10000 starting watts, giving a little extra cushion for higher surge appliances or multiple motor loads. The tradeoff is weight at 208 lb, so it can feel more cumbersome if you move it often. Like the Ryobi, it is not an inverter, so for laptops, TVs, and other sensitive electronics, plan on careful power management and good surge protection rather than assuming ultra-clean power.

Verdict & recommendation

If your priority is longer run time and a noticeably quieter generator for home backup, the Firman P08008 is usually the better fit, thanks to 12 hours at 50% load and a 74 dB rating. If your priority is getting the same 8000 running watts in a slightly lighter unit that is easier to reposition and store, the Ryobi RY909500 makes sense, especially for more occasional use.

Both are conventional (non-inverter) gasoline generators with similar core capability and a 3-year warranty, so the decision mostly comes down to how long you want to run between refuels, how much noise you can tolerate, and how often you will be moving the unit. Pick the one that best matches your typical outage length and where you will operate it.
