The X3 pushes out an R5 only because DP (and recommend) overrates Attack. The R5 is a stronger card than the X3, and your deck will do more damage more consistently with the R5 in place of the X3, because it's simply much much more durable.

Realistically, it's pretty tight between an X5 with weapon and an R5 with weapon.
