The shop I work in uses the Switch Grip. I really have not been that satisfied with the product. Idk if I simply got a bad batch of inner sleeves, but they wouldn't stay locked in and fall out in the machines or under the ball return. Myself, and my counterpart, are looking at whether or not we should transition to the IT system. We both have limited experience with that system. Aside from the extra number of steps and pieces, which do you use/prefer and why?

I use Switchgrips and I have a couple of balls/thumbs that just don't stay locked in like you describe.
I wrap a small ponytail rubberband around the base/locking tabs on the inner. This tightens up the fit nicely. They are about a one time use sometimes I can take it out and use it again without the rubberband breaking. So at about $1 for 100 of them I have plenty but I try to not take out my thumb from my strike ball to use in my spare ball. It is my spare ball that I have the loose fit issue with most all my thumbs. My yellow thumb is a problem in most all of my balls so it always has a rubberband on it in awaiting use. My black thumb is also an issue but only in a couple of balls. I am sure as I get more wear I will be using rubberbands on more of them.

I think there is more room for pitch adjustments with the Switchgrip.

Drilling the thumb deeper is not an option with the IT.

I have not tried the IT so I can't really comment any more about it.

I install Vise IT on a regular basis.
The parts are cheap.
It's easy to install and repair.
In my area, the IT system is much more common than Switch-grip.

It is probably less durable than the Ultimate and Turbo systems. I repair 2-3 IT systems per month, usually due to broken Ball-IT's or Slug-IT's.
You'll probably have to buy the Ferarri Ball Jig in order to drill a hole in the slug-IT.
Alignment and fitting to the hole for the Collar is hyper-critical to a good installation.

FYI, the IT Collars have a very subtle taper, and they go into the ball best with the narrow side down. You can find this subtle taper by trying both sides of the collar; the side that slips into the hole easiest is the narrow side.

I’ve been using the SG for years. I had one come out in the under the lanes while the ball was in transit back to the ball lift while bowling in the NY State tournament. That wa sthe last time that ever happened. Read on:

If you have one that comes out too easily, simply lay it on your bench or other table and smack it a few times with something with a corner on it like a file or a bevel knife. Doing so will leave small dents in the outside of the inner sleeve. Test the fit. The little dents should provide enough interference friction to stop it from coming loose on its own. Do this a little at a time testing after each smack because the effect is powerful ang you don’t want to overdo it.

Where on the outside of the inner are you smacking it?
Towards the bottom, top, middle or on the edge of the bottom corner?

I smack it (make small dents) halfway up the outside of the inner sleeve/slug.

I have used small pieces of scotch tape on the outside of one of my inners to tighten it up.
I will give your method a try. Thank you.

Mo uses a piece of black tape on the outside of the SG sleeve to tighten them up if need be. He says that's the only use for black tape. lol.

+1 for scotch tape. I have 5 balls that have them. When the slug is too loose on the hole, I put one stripe of scotch tape almost all the way from bottom to the surface. Then test the slug. If it is still loose, I'll add another. One of my balls have them on 3 sides. My SG was originally drilled at the PSO who seemed to have a little bit different size drilling bit. Then the inner sleeve was slightly sanded and now it is always a bit loose fit when done at the current PSO.
