I don't think it's that simple.
I'm not sure what version of the 147 you've driven, but I've had 3 different versions (well, my wife has one of them) and the ride quality varies between each one.
Pre-facelift on 15" - ride is absolutely fine but crashy over potholes and sharp ridges. The damping isn't that great IMO.
Pre-facelift on 16" - ride deteriorates slightly compared to 15" in that you more uneveness on bumpy roads which is transmitted into the cabin more than on 15s. Overall, still okay.
Pre-factlift on 17" - absolutely awful ride quality. I went back to the 16s very quickly.
Facelift on 16" with 'comfort' suspension on the JTDm 16v - noticeable improvement in ride quality IMO with alot of the jarring bumpiness filtered out. You tend to get a slight up and down motion instead, but none of the 'jarriness'.
Apologies for the strange terms used - its hard to describe the feelings and sensations you get from inside the car! But seriously, the facelift JTDm 16v with standard comfort suspension has excellent ride quality.
Daren - there's a difference in the suspension on the 16v and 8v. The 16v comes with 'comfort' settings which comprise, amongst other things, of softer springs and recalibrated dampers but the 8v does not. Comfort is superior IMO (having driven one).
"The key to this new competence is a new set of suspension settings: softer springs (with unchanged ride height), a hollow front anti-roll bar and - crucially - new dampers. These are more compliant over small disturbances but control the body's movements more tightly - exactly what was needed and, incidentally, exactly what the aftermarket Harvey-Bailey suspension kit, sold for 156s, also aims to achieve. Call it convergent evolution. Part of the 147 dampers' secret is a thicker damper rod running in Teflon guides, to reduce 'stiction'.
Now it gets baffling, for reasons of terminology. The 156 range has come with standard or too-stiff Sport suspension, but the 147 has never had that choice. However, the new suspension, an option on all versions except that high-power JTD, on which it is standard, is called Comfort. True, it is much more comfortable (as a drive in the unComfortable version quickly showed) but it is also more engaging to drive quickly because the steering is more consistent and has better feel. There's no loss of precision, no unwanted extra body roll. Calling it Comfort sends out ambiguous messages, and Alfa would be well advised to make this the standard set-up for UK cars."
