NF210 versus TRD springs

[nurburgring]

Am I right to say....

1) NF210 are more comfy than TRD springs ?
2) NF210 often bottoms out due to their softer spring rates ?
3) NF210 hardly rides any different from STOCK ?
4) Its hard to tell the difference in ride between a DF, NF and TRD spring ?
5) NF210 handles not much better than stock ?
6) NFs are by far the best compromise for looks and ride quality.

Pls answer the abv questions, elaborate if u can. It would be great to hear from real owners. My car is coming in 4 days!

Black Yaris, 15 inch alloys, rear toyota spoiler, leather seats. I paid USD$35 grand for it though. Taxes are expensive here.
