I have a two prong Valeo belt I used for a long time, and I ordered 10mm inzer lever belt a couple months ago.
It's great, not too hard to tighten and once you finish your lift flip the lever open and the belt loosens up.
I'm 100% glad I bought it now. I still use my Valeo belt also.
But the lever belt for squats, bench, strict curls and standing over head press.
But at the end of the day, it depends on what your more comfortable with.
The pros for the lever belt: not hard to clamp tight, easy to loosen, really supports you once you find the right setting.
The pros for a prong belt: easier to adjust, a little cheaper, can be just as tight as the lever belt once you get used to it.
Cons for lever belt: takes a little time to adjust it, more expensive, you have to make sure you measure your waist right or the belt won't fit you properly.
Cons for prong belt: it takes a lot of energy to get a prong belt tight, and that's energy you can be using to focus on your main lift. Harder to get the prong belt tight.
These pros and cons are just my list and opinion from experience with both types of belts.
