While my weight was heavier than my regular deadlift, maybe my weight was limited by my quads as I'm a poor squatter relative to my deadlift, and this caused there to be little involvement for my upper back compared to regular deads / partial deads. I just assumed that the more upright angle of the torso, compared to the regular deadlift, reduced the need for the scap retractors and lats to work to stabilise (although I suppose it's possible to still pull with more vertical tibia and angled torso even with the trap bar).
Which do you favour with your athletes?
The biomechanics of the trap bar make it more favorable to lifting heavier weight. Quad strength is a possible limiting factor, but I would wager that in fact you were limited by core and postural strength. If your back begins to round, you won't be as efficient transferring force into the ground while moving the bar.
For my athletes I am not a fan of deadlifts. The closest I'll come to any deadlift variation would be a clean pull or snatch pull. Otherwise everything that starts on the ground is an Olympic lift/variation thereof.
In my own training I'd probably do trap bar deadlifts over straight bar, simply because the mechanics of straight bar deadlifting are too similar yet still different to the Olympic lifts. I see it as an avenue to create bad habits in my Olympic lifting, which is more of a priority to me than being able to deadlift heavy.
Edit: Forgot to add this in my original and didn't want to make a double post.

Lots. The most I ever worked up to on conventional deadlift was 315x10, or about a 405 max. That was training my deadlift consistently for a couple years. Last summer on a whim I worked up to 185 kilos for a double using the low handles on a trap bar. While battling a sinus infection and not having trap bar deadlifted in 3 years. That should put some perspective on the favorable biomechanics.
