Just what the above mentioned. It's harder to field strip. Keep an allen key handy.
Not sure about the Taurus pistols, but my Colt Government XSE with a full-length guide rod requires no tools to field strip (certainly not a allen key!). A plastic bushing wrench certainly makes it easier, though.
That said, this Colt has been 100% reliable and incredibly accurate, so I've seen no need to switch out the FLGR.
