There is some update with this topic, so I'd like to share my findings to help other forum members who might be looking for a USB LA in the future. I know I've had some trouble finding practical information to make the decision.
To sum this up, my main concern with the 4032L following all the other info I've received from the helpful member of this forum has been the actual maximum signal frequency it can handle. The claimed 150MHz seemed too optimistic for the way the output connector is arranged (with GND signal on only one edge of the connector). Lucky for me, member maginnovision was very helpful, and went ahead an ordered a few parts to allow him to test with various frequencies (and I would l like to take the opportunity to thank him once more for all the help). My concern was that the highest frequency won't even reach 100MHz (as I've posted in the last post), and that there are significant differences between channels since ch0 is close to the GND return path, while ch16 is very far from it.
maginnovision did quite a few measurements, but I won't detail them all, instead I will jump to the punch line. According to his findings, with the original leads provided with the 4032L, the maximum frequency you can use is ~90MHz on the channels closest to the GND pins, and ~60MHz on these at the other edge of the connector. This is all with only a single channel used at a time, and will obviously get somewhat worse with multiple channels used at the same time.
In comparison, as can be observed in the video I've posted in one of my previous posts, the DSlogic Plus with the shielded leads seems to support up to 200MHz frequency at the input. I don't need to go that high, only 50-100MHz at most, but I'd like to minimize the chance of missed edges, so the DSlogic seemed like the better option in this regard.
The main issue for me with the DSlogic remains the constant threshold on the CLK pin. However, this I can solve using a level shifter IC. The lower channel count is a point against it, but I can live with it for the foreseeable future. Therefore, I've decided in its favor and placed an order for the DSlogic plus from their website. I've contacted them via email and they have confirmed they are sending the Plus model, despite the site not being updated yet.
I would like to thank you all once more for the help, it was crucial in helping me make an educated decision instead of going on a hunch
