One thing to keep in mind with a CTL or SS, even if it wasn't hydrostatic (which would be a real pain), you would still run at max throttle for anything involving the aux hydralics.
I know I'm playing up the advantages of a true power shuttle, but when you add either a constant hydralic load, or a PTO load, your in the same boat, and then the HST is 100% the choice.
I would 10 times out of 10, choose a HST over a traditional clutch and gear machine that doesn't have a shuttle (we arent talking tillage machines, hence loaders). Probably 9 times out of 10, choose a HST over a simple dry clutch shuttle; and 5 out of ten, choose Power shuttle or HST, case dependent. No experience with CVTs. For a true grading tractor with a loader (ie JD-210) I don't feel a PS has any disadvantages over an HST, as they rarely (if at all) came with a PTO. For general use, it really depends, if you are going to 85% use loader and box blade, or small plow/disc, PS. If your running a bushhog/broom(unless it has a dedicated hydralic pump)/tiller; and also doing a lot of loader work, the HST is the way to go.
Note, I have no experience doing real ag tillage or bailing;
Edit: I'm 100% Not saying a PS won't do those things well; what I'm saying is if your already running PTO RPMs, the PS doesn't, IMO, then offer the advantages it does with foot throttle, reduced RPMs when traveling,
