If this is purely for use at home, don't forget about the time/effort of maintaining a small gas engine, cost of repair/replacement, etc when comparing it to the cost of getting a hardwired 30-amp receptacle installed. I don't know about where you live, but I live in a urban area and having a contractor generator running would make me very familiar with my neighbors, but not in the way I'd prefer.
The key differences between a contractor grade generator (like you linked) and an inverter generator are: quality of the A/C power, loudness, and efficiency. A contractor style generator has to run at full RPM in order to maintain voltage/cycles (~60Hz)...an inverter generator can change engine RPM with load, as it maintains the power cycle through a more intricate process. This is also why the power "quality" out of an inverter is better, they always put out a true-sinewave...while a conventional contractor generator's output varies if the engine stumbles or slows due to the load. Does the power quality matter? That depends on what you are powering, how much does it cost to replace the high tech digital control package, the ducted A/C in a 2019 International, or your TV?
Here is a comparison, obviously it may be a biased source as they want you to buy the inverter generator, but it doesn't make the overall information any less valid:
