For two same-velocity loads using the same bullet and two very different powders, the felt recoil will be heavier with the larger powder charge.
This has to do with simple physics. The "ejecta mass" or material expelled from the gun as well as the mass and velocity of the projectile determines velocity.
Example 1: If Unique and H110 are loaded to give the same velocity in a .357 Magnum, .44 Magnum, .45 Colt, etc, the heavier powder charge will recoil more. The powder charge weights will be very different because Unique is a medium-fast flake type powder and H110 is a slow ball-type spheroidal powder.
Example 2: .38 Special, .38-40, .44 Special, .44-40, .45 Colt, etc. were originally loaded with blackpowder. The same velocity loads using smokeless powder recoils less.
