I would lean towards the 8250, just to be near the 8080A ball park. But, I think the 16450 and 16550 are both drop in replacements for the 8250?

Yes, me too, I prefer 16550A UART or equiv, easy to interface, easy driver, cheap, easy to get!, built in baud rate generator...tom...

Yes, nice set of features. I’d prefer the dumbest UART possible – all values set by jumpers/switches so no software init is required – but that may be a bit too old school.
