I’m both a Debian bookworm & Ubuntu jammy user. My Lubuntu system has a later version of LXQt than Debian testing, as Debian testing still has the LXQt that was used by Lubuntu 21.04.
Note: I’m referring to Debian bookworm which will be Debian 12; as that’s what I use on my Debian system; Lubuntu 21.04 had the same version of LXQt that is found in both Debian 11 bullseye and currently Debian 12 bookworm.
Yes a later version of LXQt sits at salsa.debian.org but it’s not yet being packaged for sid let alone further down the line (we hoped it would get to sid so we could use it Lubuntu jammy!)

I was a Debian GNU/Linux user before the Ubuntu project even got started, but back in those days I wouldn’t touch any Linux distribution that didn’t have GNU in it’s name, Debian used GNU/Linux at that time, so I was happy. It wasn’t until around ~2010 (ie. six years into the Ubuntu project) that i finally started using Ubuntu Linux, so I was a late starter.
I liked Ubuntu (and to me Lubuntu is just a Ubuntu system, so it’s common for me to refer to Lubuntu as Ubuntu) in that most of the time I can act as if I’m using a Debian GNU/Linux system, even though really I know it’s rather different. For servers, I find it harder to use a Ubuntu system over Debian, but not so with Desktop systems as really Ubuntu is just easier. If you want closed-source drivers, Ubuntu systems have ubuntu-drivers & other easy scripts that just save time. If I completely stuff up a system, I know I can get both a Debian or Ubuntu system back operational, but it’ll be less work & faster to get a Ubuntu system back in operation (here I’m talking about a bad stuff up that requires re-install).
I’m very pro-Debian… in fact I got started contributing to Ubuntu because I was having trouble getting started contributing with Debian, and found Ubuntu easier… I’m a Ubuntu Member, Lubuntu Member (inc. on Lubuntu Council), but I still do cherish when I finally got upload permissions to a Debian project. I spend far more time with Ubuntu/Lubuntu (I’m involved with more than just Lubuntu) than I do with Debian… but I love both.
To me anyway, I still find desktop system easier to manage with Ubuntu, and for some reason tend to prefer using Debian for servers (even though Debian is more work to plan for than Ubuntu with its very predictable release schedules!)
I’m happy with both, would be perfectly happy using either of them (if unable to use the other) but in most cases Ubuntu systems are just easier.
I seem to remember Ubuntu being advertized somewhere as “Debian made easy”.
FYI: Also note with Debian I don’t just use Debian testing as my initial paragraph stated; the first machine I touch every day runs Debian stable, it’s also the last machine I usually touch too, though most of the day I’m using Ubuntu systems. On this Ubuntu jammy system (my primary PC), most of my file-storage is being served by Debian bullseye. This system is dual boot, but beyond the jammy I’m currently using the other system I have installed is focal (ie. Ubuntu development and lts). Both systems have multiple-desktops installed & my most used is Lubuntu/LXQt; but this isn’t my only PC.
