17" wheels will be prone to pothole damage and ride quality will suffer because of having less sidewall compliance. Stay with 15" wheels if ride quality is a consideration.
A lot of the problem with the ride is that the ride motions are insufficiently controlled. The front springs are too soft and the damping is weak. You'd think that would give a soft ride ... but there is not very much suspension travel available, and it leads to the front end slamming into the bump stops all the time. It also leads to sloppy body control when changing directions (lots of body roll ... and the suspension comes close to hitting the bump stops when doing so) and the fore-and-aft pitching on acceleration, changing gears, braking, etc.
If you are going to go to the trouble of taking things apart to change front springs then put on better struts as well.
I can't speak for other choices but I can only comment on what mine has (and which has been in there for 100,000+ km). I opted for the complete Bilstein B14 coil-over suspension kit, and four OEM 15x6.5 rear rims, and Falken 195/50-15 tires all around.
It rides and handles the way it should have from day one.
