For a rangefinder style, there's the Fuji X100 series (the latest being X100V). They are not really pocketable though.
But for a big sensor compact that is truly pocketable, nothing beats the Ricoh GR series with its APS-C sensor (the latest being the Ricoh GR III). The older model (GR II) can still be had for under $400, which is a screaming value.
