I do, but I also pull sumo and conventional. I think a lot of it - once you get past any mobility issues there may be and taking into account particularly disproportionate limb lengths if that’s an issue - is down to weak points and technical issues. I think generally if there is a large disparity pulling with one style compared to another that points to one or more weaknesses or technical problems.
The main barrier to sumo pulling I’ve seen is that people often don’t understand how to lever the bar off the floor with their hips in the first third of the movement, and instead just pull conventional with a really wide stance, leaving their shoulders way too far forward. Of course, that’s a horribly weak position to pull from so it ends up feeling like sumo is just a weaker stance when what’s really happening is they aren’t executing the lift properly. To make matters more confusing, sumo does actually often feel shitty off the floor but mostly because it’s a slow, controlled ease off the floor while sitting back and making sure your shoulders are behind the bar, compared to conventional being quite aggressive early on and not living or dying by whether or not your shoulders are behind the bar.
Geez, that got long. Sorry.
TL;DR before changing your DL style, make sure your technique is good. If it is and you’re still having issues, then try a different style. In relation to semi sumo specifically, I think it’s best left until you can pull conventional and sumo with decent technique. I say that because my experience of semi sumo is that it has more potential to get sloppy than conventional while still letting you move reasonable loads so just for safety you want to know you can do what is necessary before you start mucking around with that.
