Pretty easily. The biggest points are:
- 0cp vs 3cp
- Free vs 60 muni upgrade (can be lost if squad dies but increases combat effective so comes out in the wash)
- Always active vs activated ability requiring an RNG event to happen near your G43 squad that lasts a few seconds for maphack that lasts a few seconds.
As has been pointed out in other threads, parts of the "maphack" part of G43 is actually available intuitively via radio intercept. If I see where your first Gren squad spawns, I have a very good idea where you're going. I can see where your mines go down so I know where you're holing up and where you hope to blunt a flank.
You're paying for weapon upgrade. You get this ability as a bonus. It comes at 3CP because of the weapon upgrade.
You have chance to use it after each engagement. If you don't do it it's your own fault.
It shows EVERYTHING on the map for couple of seconds. You'll be able to gain this Intel after next fight as there are always some wounded models on the ground. Again if you don't it's your own fault.
Lastely I can tell when my opponent is going without Radio intercept based on the map I can roughly say what's going to build seeing his initial units composition as well.
