If you don't reload, or your ammo gets lost, you will have a much easier time finding ammo for one over the other.

To me, you can produce about all the "boom" you want, loading the .45-70 with big, heavy bullets. The Marlin 1895 is a relatively light gun, anyway. I personally don't see the need for a .50 in an 1895.

The 1886 clones are stronger and the guns generally heavier. I think they'd be a better choice for the .50.

IMO, but others may disagree.

The 50 AK functions at 35,000 psi with a 400 gr bullet at 2000 fps
The 45-70 with a 400 gr bullet at 2000 fps generates just under 45,000 psi
Both safe in a marlin 1895, recoil is identical for obvious reasons.
The choice is yours, don't exceed 45K in the marlin no matter the caliber and both you and the rifle will function for a lifetime .

A 400 grain bullet in .45 caliber will have a higher SD than one in .50 cal., .220 vs .272, which would increase the possibility of the .458 projectile penetrating deeper. A .458 of comparable SD to the .50 would have to weigh about 325 grains.

An LBT bullet in .50 cal would certainly have the meplat to hit hard!

I've used Beartooth Piledriver Jrs at speeds up to and slightly over 1800 fps in my Guide gun, the penetration is tremendous, and the Piledriver (525 grains advertised, mine weigh in at 540 grains) at 1550 fps dig really deep. Neither load is over 36 Kpsi, so there's more on the table.

Recoil can be a real snot-knocker...

Personally, I'd just stay with the .45-70 in the Marlin platform. I'd have to have something that the perceived recoil was not so vicious with to go to any higher performance level.

Do a comparison, the difference will be more momentum than KE based.

Penetration?

Here's a video of some penetration:

If you're only going to shoot 400 gr bullets, no reason to go with the 50. But, for a given caliber there is only so much tissue it's going to disrupt and if you want a bigger wound channel, you have to go up in caliber.

For 450-500 gr cast, the 50 AK is the better choice.

The 450 Alaskan with 400 gr FP Alaska Bullet Works FP bullets or Hawk heavy jacketed FP bullets in a pre-warModel 71 tends to even the playing field.

Fred Huntington noted years ago that Harold Johnson-who smithed the original 50 Alaskan-said that it worked on
most anything in Alaska-with his 50 BMG bullets truncated forward and handloaded.

I would feel more comfortable with custom bullets in the 50 Alaskan. In Alaska. Pre-war Model 71 Winchesters? Personal experience.

The numbers are pretty good but the same issue that many others have overlooked in touting their own favorite round in that they don't compare at equal pressures. These are both very good cartridges but when loaded to the same pressure the 50AK wins by a fair margin. Would any animal notice the difference when healthy probably not but a wounded bear in the thick brush and I don't think we could carry a gun that would give full peace of mind. grin
