First, there is the question of reliability. The glue-together seam must be perfectly clean when the glue is applied for a good bond. A small speck of dirt or any grease on either surface will weaken the seam and may cause it to fail.

Second, the boot must be left undisturbed for up to an hour while the adhesive cures. Otherwise the seam will not hold. In the bolt-together boot, glue is not used to seal the seam. The manufacturer supplies an extra quantity of lubricant to replace grease that is continuously lost during normal operation. This necessitates periodic relubrication.

Third, Its very difficult to thoroughly clean and inspect a CV joint on the car. Some contaminated grease will remain in the bottom of the joint regardless of how much solvent is sprayed or brushed on the joint.

Fourth, and most importantly, a joint with a bad boot and contaminated grease may be damaged and need to be replaced anyway. It's impossible to detect certain types of cage damage and race wear without removing the joint from the car.

I've used the split type before on my '91 Accord and didn't like them. They didn't hold the grease long. And however little the screws weighed, it was still enough to cause a vibration at freeway speeds. I ended up just replacing my axle instead. A rebuilt axle cost me about $50 and took me less than an hour to replace.
