Generator Choice: Final Four (?)

Absolute MUSTS: 240 volt (L14R30); under $1200; Inverter; Closed Frame. Anything above 4,000 running watts will work fine.

Within those limitations my primary concern is noise, Searching Generator Bible (and 20 other sources); my candidates are Champion 201238, GenMax 55001, WEN DF6801X, and Pulsar PGDA70BISCO

The Champion and the WEN are gas only and are claimed to running at 64 dBA.

The GenMax and Pulsar are dual-fuel and are claimed to run at 62 dBA

Any thoughts or experiences are appreciated,

The WEN is by far the most attractive option but I am worried about actual vs advertised sound level. I saw one video review that measured the WEN at mid- to-high of75dBA. Which is it??
