Unfortunately, the improvement only upgrades them from "is this thing a joke?" to "throw it in the trash".
I did a mini comparison of the Baofeng to a well known Yaesu radio on a different forum (link below). The Baofeng was totally outclassed. This comparison was not about features, it was only about performance.
On that other forum, I also did a post about an antenna stand I made for a J-Pole antenna. J-Poles perform well. You can mount one on your house or take it portable (mine is a two piece takedown model). You can't mount a J-Pole on your car however.
