I own tow Honda 2000 gensets..nine years with zero issues
When I made my purchase there were not many options to choose from versus what out there now
No way would I spend $2700 for the Honda 3000is with 25 amp capacity (surge).
The P4500 has been out a while and appears to be well liked by those using it.. rated at 37 amps and weight of 98 lbs
Price $1250 from CW
I would also look at the Predator 3500.. it’s also a nice inverter genset at 102 lbs weight
Price.. around $929
Here is a link comparing the P4500 versus the Predator

You can run ONE roof AC with either unit and other 120 volt items using some thought process on power management
