Regarding the BBB/BBG, in the last 3-5 years the RPis have gotten significantly faster (RPi3 & 4) and gone 64-bit whereas the BBB & BBG haven't changed much (aside from a bit more eMMC and a very minor CPU bump) since they were launched. These days the 1GHZ 32-bit AM3358 (BBB RevC) is comparatively much slower and with only 512MB RAM, that's a lot less than a stock RPi 4.
Having said that, the BBBs are a great device! They're rock solid and have far better I/O options than the RPi: 4 UARTS, multiple I2C, SPI & CAN buses, EHRPWM, a ton of GPIO, 2x PRU processors, LCD driver, both USB and USB Gadget, oh and of course, the onboard eMMC is great compared to booting from an SD.

So I'm psyched about the Beagle-V.
