cp2102 is my standard recommendation, as they are cheap, do what they're meant to do and cause no trouble. FTDI were good, but they went apeshit with the drivers bricking non-genuine devices, and I don't wish to support them if at all possible. Prolific have always been troublesome, and their proprietary drivers refuse clones these days (which broke my chinese usb-rs232 dongle). ch340 is very popular these days, but I've found they have little tolerance for slightly-off or jittery clocks.
