PDO vs. mysqli

Up to now have just been working with mysqli, using prepared statements, passing parameters, etc., but, was looking into PDO now, and seems to, among other things offer a more dynamic form of parameter passing, etc. Either way, was just wondering if there's are any specific reasons should stick to just working with mysqli directly, or if should switch over to making use of PDO more often/most of the time? AFAIK, most servers should, nowadays handle/support PDO in any case - am working with XAMPP here on my dev machine, which is windows 10 64 bit, but anyway.
