    Each has its own pros and cons. You would need to weigh ease-of-use vs cost for making your choice.

    The PL2303 is the cheapest of them all. There are a number of 'clone' (fake) Chinese adapters doing the rounds with terrible drivers which fail within weeks to better ones which last longer. Driver support, however, is questionable (source: forum posts across the internet).

    The CP21xx is cheaper and has much better drivers than the PL2xxx chips. Availability isn't great though. Driver support has improved over the years but still lacking compared to FT chips.
    Here it is Sparkfun

    When you're looking for reliable performance and great driver support, FT chips are surely the way to go. They are a tad costly for sure but generally available everywhere - either as breakout boards or as FTDI cables (with a 6-pin female headers).

    IMO, if you are willing to shell out a few bucks, getting an FTDI board is your best, no-headache option (but then, I do have a PL2xxx cable lying around which hasn't failed me so far :)).

    The FTDI ones have been around for a while now and seem stable. Poke around and you'll find them on already assembled on breakout boards to jumpstart your prototype. I keep one like that in my parts box, bought it without any need "just in any case."

    Cheapest breakout I found on Fleabay
