I guess that would be personal taste. There are two types in addition to the logo/no logo, the spear covers and the replacement spears.
Wyckoff Chrysler has the replacement spears on sale..

JJ Products has a good price on the spear covers..

The spear covers are very easy to install, just stick on over your original spears, the replacement spears require removal of the orignal door spears.
Check e-Bay also.
