Thanks and keep on truckin!
Unsprung weight is not the same as rotational mass. The reduced weight of the wheels will have a few effects -- these effects are very slight, so some may be noticable and some may not
-- brakes more effective due to less rotating mass to slow and less overall vehicle weight, but this will also affected by the tires you choose and their available traction
-- better acceleration (for the same reasons, also affected by available traction)
-- better handling due to suspension's ability to respond more quickly to road surface (less unsprung weight), and less overall vehicle weight
-- anything else that I may not have thought of
The stock steelies on my 2006 2wd are quite boring, but I don't really feel any better or worse about myself because of the vehicle that I own, as long as it's not a thrashed rust-bucket POS (everyone has their minimum standards LOL). These wheels aren't ugly, they work fine for my needs, plus they probably won't catch the attention of any thieves, and that's all I really care about. Everyone's different... enjoy the new wheels!
