I kind of felt the same thing when I replaced my tires. Front end was all OK, shocks, alignment, DSS etc. I think it might just have been because I got used to the old tires wearing slowly and didn't notice the handling changing over time.
New tires dramatically changed the handling. Took some getting used to.
I did lose the death wobble tho with the new tires. Used to hit a particular expansion joint with the old tires and got the wobble all the time. Never since the new ones.
Hope it helps
