I've only tried Drol once, and it was liquid oral.

Strength gains were equal.
Water was heavier on drol, though the time I ran it I was on a lower dosed AI, and it was combined with Sust.
I noticed more size on Dbol. The pumps and aggressiveness in the gym were more intense.
I felt a bit more sluggish on Dbol initially, Drol I didn't get any of that.

Out of the two, I'd opt for Dbol. Out of any oral, I'd choose Anavar.

If I were running your cycle, I would extend my Drol to 6 weeks and use 50-75mg PD. I find gains were more maintainable at a lower and steady dose/duration rather than higher/shorter.
