Despite the power of the weapons from 40k, the real question is, can the borg adapt to them? We know even borg drones can carry personal shields that could make them completely immune to phasers. Why not every other weapon 40k has to throw at them?
We also know that ships in Trek can move at close to relativistic speeds in space, including borg cubes, while everyone in 40k spend weeks traversing a single system at STL speeds once they leave the warp.
Accelleration to said speeds also go to Trek, where all ships move so fast they need inertial dampers to avoid turning their own crews to chunky salsa. Do 40k ships even have inertial dampers? They certainly can't pull hundreds of G's of acceleration.
Range is anyone's guess as both Trek and 40k have been highly inconsistent on what the effective ranges for their ships are.
Firepower? Trek torpedos are nukes, and not small ones either, the quantum torpedo's are 64 megaton yield if my memory serves. Easily as powerful as the torpedoes on an imperial ship.
On the other hand, a 40k imperial battleship armed with large numbers of regular (if very large bore) cannons on its broadsides is considered powerful and dangerous. To put it bluntly, this shows that ranges and firepower of 40k ships are fairly anemic.
Let me give you an example. A modern railgun can push a projectile up to 2500 m/s or so. Even with supertech, 10.000 m/s for a projectile would be insane. Nearly enough to shoot its projectile straight into an orbit. So most likely all those guns on the imperial battleship will have slower projectiles.
In trek, combat is said to easily be 10.000km to 20.000km ranges. Nothing fancy for hard scifi, but it gives us an idea of the ranges used in trek.
Using the extremely generous 10.000 m/s projectile assumption from before, the shots of a broadside on that imperial ship would take 1000 seconds to arrive at a target 10.000 kilometers away. That's nearly 15 minutes, during which the target can try to evade, shoot back or leave.
Assuming slower projectiles, like 2.000 m/s (more than you will get without using a railgun like the tau) travel time for those projectiles will be nearly an hour and a half (83 minutes).
To put it mildly, the effective range of those guns, is a few hundred kilometers at most. Not many weapons on ships in 40k outrange those guns enough to make those guns laughably useless, so there likely aren't many weapons effective at tens of thousands of kilometers range.
Also, there's lots of weird weapons in trek that could likely butfuck anything from 40k, like that thing that tore a hole into subspace in the fabric of reality, tractor beams (do they even have those in 40k?) which can even large vessels, the protomatter bullshit of the genesis device that can rearrange an entire planets molecules (which should be enough to erase even a necron tomb world from existance), time travel shenanigans, transphasic shit that lets ships or torpedoes pull necron style inability to interact with or be interacted with by solid objects until a time of its choosing and so on. Hell, a Klingon Disruptor works by destabilising the molecules of its target to induce spontaneous nuclear fission. Sounds a lot like what necron weapons do, doesn't it? And its something the borg presumably CAN adapt to.
I'd say the jury is out on who has straight up more firepower. But since the fighting will likely take place at ranges where the 40k ships can't effectively shoot back, due to the trek ships superior range and mobility, its kind of moot.
Also kind of makes those ramming attempts kind of ineffective.
Besides we've seen Borg cubes shrug off sustained assaults from a fleet armed with nuclear level weapons, we've seen them repair damage from having a large chunk of its hull cored out by a bombardment of said nukes, in minutes. I wouldn't be so quick to assume a cube would be rendered completely dead from having a ship hit it.
