The only time I dealt with pull-up belts, they did not work. The adjuster was wedged next to the seat and did not really tighten or loosen. I do not know what application they work well in but it ain't ours.
We've run latch-links, cam-locks and the newer style enduro belts. We ditched our latch-links after the first race, cam-locks are way easier to deal with.
Re-certified belts are barely discounted. Some manufacturers just ask you to send in the certification tag. So it's mostly a discount program. I do not think FIA allows recertification. My last two sets of belts have been FIA, they are a little more expensive but have a longer life making them less expensive over time.
My old belts were G-Force camlocks pull up belts which worked fine for us. Like this: https://www.summitracing.com/parts/gfr-7000bk
The biggest issue we had was varied driver size. I am a small dude and the pull straps need to go back through the seat to get tight enough for me if you just pull to the side in front of the seat the belt won't get tight enough.
I also HATE side swing belts, I want the buckle on the sub-belt.
Most recently we upgraded to the newer FIA belts from G Force and Racequip.

My buddies car got the G Force belts in November and I installed the Racequips in mine in January. Having the adjuster and camlock tab in one piece makes the belt easier to use and adjust. The belts are about the same and a much more affordable alternative to the Schroth. Both belts are mostly 2" so I do not understand why the shoulder belts are 2" & 3" like why not make the whole thing 2"?
I got a deal on the Racequips and was able to get a 2019 belt in January making it good through 2023 or 2024. Point was I did not want a belt that already lost a year since I was buying so early in the year.
