Here are two 40K Weapons:
HELLGUN (Imperial Guard)
Range 24"
S 3
AP 5
Rapid Fire
SPLINTER RIFLE (Dark Eldar)
Range 24"
S 3
AP 5
Rapid Fire
Both are sort of basic small arms for their respective forces (the Hellgun is used by IG storm troopers as their basic small arm). Both function precisely the same way in game terms but have very different "fluff" with one weapon being laser based and the other firing kinetic rounds.
In our home grown rules over time we've developed a sort of database of weapons in various categories, everything from different grenades to small arms to heavy AFV weapons and even off-table fire support.
Here's the question
One can take two approaches in presenting this information to players as far as a reference sheet goes. One can be very specific and have separate data entries for weapons with the same game data (eg the 40K approach as far as the Hellgun and Splinter Rifle are concerned).
Or one can take a generic approach and provide generic line items and not worry about the fluff name. To continue with the example above, one could have Rifle Type III which would show the information above in a single line item and the individual race fluff would show that the Splinter Rifle is a Type III Rifle and the Hellgun is a Type III Rifle too.
For example
RIFLE TYPE III
Range 24"
S 3
AP 5
Rapid Fire
IIRC some "generic" oriented rules take this approach.
Another example could be a light, short ranged, anti-tank weapon and whether it fires a bolt of plasma or a super high tech rocket the stats might be the same (eg LAW IV or whatever).
The advantage of the weapon-specific stats is that you have..the
weapon specific stats. The advantage of the generic approach is fewer data points to remember and greater flexibility for "quickie throw-down" games between friends ("Oh, those guys count as being armed with Type III Rifles while the AT figure counts as having a LAW IV weapon.")
Which do you prefer if any or does it not matter?
NOTE: I'm not saying dissolve the differences between various weapon types
I want my SAW to function differently from an AT-4 or their sci-fi versions. But maybe it doesn't matter if my sci-fi automatic weapons fires streams of energy bolts or kinetic rounds if they have the same range and armor penetration capability.
OTOH, some folks might object to generic weapon names and stats (like my kids do!) :-)
