is this worth buying

I think, or should I say in my experience, you get what you pay for.
I like the Skyjacker leaf spring lift, do not care for their TJ lift. Seen a lot of guys do the Rough country kit on their CJ's and most have replaces the springs and shocks. I think most guys with CJs keep them a long time and a bad set of springs is a bad set of springs.
I will tell you do not go with the BDS kit. They are hard as a rock, but they do last a long long time.

That is the exact lift i have and i think its great, a little rough, but its part of the jeep experience. I have 36s and I just had to do a little bit of trimming on it. It still flexes very well when it needs to, but it stays solid on the roads. Its possible you will need to get a Transfer Case drop on yours, since it is a 5, but dont quote me on it. Its personal opinion though
