CaseCrown Lux Glider - Black + MediaDevil Crystal Clear screen protector = Perfect combo (in my opinion)
Had to buy the case from the US though so it took a couple of weeks to come through, but I can assure you, it's the best case I've had on any of my phones.

Casewise I've tried these so far:
Gear4 Ice Box Edge Case- Rubbish, as the plastic shield at the back scratches whenever you take the phone out (phone scratches it). Also I'd imagine the dust build up would be quite bad so you would need to take it out for a clean occasionally. The same can be said for any of these rear plastic covered cases- tried a Rocketfish Reveal at CPW and that scratched as well. The Griffin version would also be the same.
Tech21 Impact Snap- Didn't fit perfectly on the phone itself and was slightly skewed out on the one side. Plastic felt cheap, very little grip and top and bottom sides were exposed (however most snap cases are like this).
CaseMate Barely There- Not bad at all, have been using it up until I received this CaseCrown. Only gripe is that the rubber textured coating has already started to wear off on the corners and edges after 2 or 3 weeks usage. Probably won't look great if you want to keep it long term. Also top and bottom sides are exposed here like the Tech21.
Cygnett Second Skin- Loose fit which was immediately noticeable. It's entirely soft rubber so this would only get worse through usage. Have used flexible cases in the past and should have learnt my lesson really as any dirt that get's caught between the case and phone will just flex and wear against it. Had this happen on my iPhone 4.
Regarding SwitchEasy- Avoid! Tried one on the iPad 2 that I had and that scratched like crazy. In fact any sort of shiny plastic backed cases I'd avoid as they'll scratch quite easy making it look terrible.
Sorry for the the long post, but just thought I'd share my findings as it might be useful for some. However, this is just my opinion. Some of you might have had a good experiences with the above cases
