Well, that is going to depend on your personal tastes.
There are plenty of ups and downs for either type of ignition.
Points are much simpler to troubleshoot than an igniter, but require a lot more routine maintenance and a bit more fuss to set up.
Back in the day, everyone had to deal with points, and so it was a skill that everyone was forced to have. It's not exactly intuitive to set points exactly right, and there are many things that can go wrong, even basic things like screw heads getting stripped.
Basically, it takes a bit of experience to get really good at setting points. And nowadays, it's getting harder to find a decently manufactured set of points. Some of the stuff coming out of China is pure garbage, and can make a simple point replacement job a total headache. Once you get experience and know what you're doing, it is satisfying to get it set exactly right and have the motor purr nicely.
The majority of people probably like the set-it-and-forget-it benefits to electronic, but if it starts to fail, it's a bit more involved to troubleshoot properly... or expensive to replace everything.
The factory system is pretty good and probably a bit more reliable than an aftermarket ignition, like the Dyna S. If your motor uses a 1-phase charging system (rather than 3-phase) you will probably want to stick with a factory system.
A Dyna S system has the pickups and igniter all in one unit and will come with it's own rotor. The downside is that it will require 3 or 4 ohm coils. The Dyna S uses a lot more power than the factory system. The Dyna S will probably be cheaper than a Kawasaki system, but if you require a charging system upgrade, it will get a little more expensive. I don't expect you will absolutely need a charging upgrade, but it's a small possibility to be aware of.
The factory system requires the 2.3 ohm coils (which you probably already have) plus a timing plate with a set of pickups, a reluctor-rotor in place of the points-cam, and an igniter. The igniter might be expensive to get. Years ago it was relatively cheap and easy to make an igniter, but the correct parts to easily make one are getting harder to find.
