Other than the fact that you're not going to get your giffgaff sim to work until either someone manages to crack the unlock codes or you've had it connected to orange for 3 months and pay them £20 I think it's better than the blade.
Screen is the same resolution but so much easier to read with the extra size and is definitely a bit faster and 'snappier' in use also the wifi doesn't drop all the time and connects properly when the phone wakes, I have to manually refresh my OSF if it's been left for more than a couple of mins,
I bought mine because I dropped my OSF and the touchscreen stopped working, I spent the best part of a week trying to get a turbosim to work but ended up buying a new digitizer for the OSF. As soon as I can unlock the monte carlo I'll use it as my main phone though.
Edit: battery life seems much better, still on 75% after 3 days of mucking about, connected to wifi, downloading lots of apps and playing with it lots BUT I hardly had data turned on as Orange is so damn dear and didn't make many calls cos no-one has got my orange number.
