You can tell the difference in .55 lbs? Man that difference can change with accessories.
The Drenalin is shorter at 33" to the 34.5" of the Marquis. You get a better grip as far as I'm concerned over Mathews bulky grip. One of Mathews biggest downfalls as far as I'm concerned. I've always said that but coming from a long line of Hoyt's...I'm a thinner handle fan.
Diamond is slightly faster, 320 for Mmmm and 324 for the Marquis.
All the Drenalin specs are followed by a (Approx) (could be worse, could be better) the Marquis are not.

And the Marquis just looks nicer with their camo options.
OH, and let's not forget price.....Fanfare, it's a very impressive bow at a very reasonable price. Why spend money you don't have to. You can upgrade your accessories with the savings.
I hate seeing someone buy a top of the line bow and then accessorize it with unsatisfactory additions cause they want to save. [8D]
