The Pulsar is pretty close, a few specs here and there..
I liked the Cummins overall and the Westinghouse has 2 version, one from 2018 and the newest version as is the Cummins..
That would be my first choice , as for longevity, use good oil change it and so be it... I have Hondas with over 2500 hrs and even these models but I use them hard and change oil every 100 hrs..
I use the death out of this

a $600-700 unit..
Simple no electronic display, quiet, at full load at 3meters 62-64ish, 57-59 in eco, added my own hr meter.
It is just marginal when running a 13K AC and refridge and tv is OK.
it will run a 15K but it is running hard when compressor cycles..
But it runs like a top with lots of hours, it runs 5 days straight with ac on at times, I only stop it to change oils on long trips in hot weather..
Good luck on a generator purchase >>>>>
