To be honest I think the MS Wheel comes in second. I have had one and a Mad Catz and a Logitech one and i definitely think the Logitech wins in the end.
I agree there are some things that could be added to any of the wheels, the missing left stick is a problem as you say.
I think the Logitech has the best construction, the MS wheel loosens up a bit after a time due to the plastic bearings it uses whereas the Logitech has steel bearings and rack & pinion (ish) steering, it is very positive and the FF works well in TDU and PGR. It also has a sensitivity adjustment on it which is helpful in TDU.
I did have to buy my one on the web from Germany but that was a while ago now I am sure they are available here now. Definitely worth the investment.
Only my opinion though, I would love to hear what other people think.
