Personally I'd have been happy if they kept the 7.62N L1A1 instead of the 5.56 F88, but that's just me and my desire to see a target obliterated rather than tickled to death....
I do like the ergonomices of the F88 a bit more though as it's much easier to use on handed than just about any other weapon I've every laid my greasy fingers on. Some say it's an uncomfortable weapon to use, but I think that's mainly because it's a bullpup and nothing is where you'd expect it to be on a conventional weapon. Adequate training fixes that. It's also one of the easiest weapons to carry on patrol because of it's centre of balance being right at the pistol grip.
It's only other drawback, at least in the earlier versions, was it's inability to fit a GL or alternate sights and accessories (this wasn't much of an issue at the time though as VERY few accessories were available, let alone issued).
