No matter how hard I try, I cannot name more than 4 weapons for whole EW (L30 could be fifth it is was ever useful, but well does not really matter for following anyway).
The problem is that to make EW any fair, they need some rather expensive weapons to be compared with top of other categories, and to make it ever useful it needs some cheap as well.
This basically means there is almost no way to balance their cost and usefulness and give EW players some progression, compared to 9001 SG models (though good deal of them are lame F2 weapons copying various WW2/Vietnam models, at least something is there).
Another problem is the quite limited use in original series, leaving quite little choices. However Fonline (and some wrong F2 design) reduced this number considerably.
Here's a list of existing EW weapons in Fallout universe (red being unavailable):
Laser Pistol (+magneto)
Plasma Pistol (+ex)
Laser Rifle (+ex)
Gatling Laser
Plasma Rifle (+turbo)
Pulse Pistol
Pulse Rifle
This means there is 8 weapons available in Fonline and 11 weapons total.
Optimally there would be about 4 tiers of weapons (beginner, mass used, hq crafted and uncraftable).
With 8 available weapons there would be 2 per tier, not really bad, as some choice is left.
However in reality, of those 8 weapons, 3 are upgrades that do have nearly no effect, leaving 5 weapons per tier, and so it leaves nearly no choice ( almost 1 weapon per tier, there being really just competition between laser rifle and plasma pistol as they are in about same category ).
Why did I say upgrades are meaningless?
Let's iterate them:
Magneto-Laser Pistol - add penetrate perk (dividing DT by 3, round down), in the best case it's 50% increase!
However that is in case of targeting tesla armor, and difference is making ~1 damge in ~2 damage per shot.
In case of Metal Mk2 which is commonly used protection from lasers, it improves ~4 damage to ~5 damage, still way too poor to see those pistols perform different roles or be considered as different tiers.
Laser Rifle (Ext.) - double capacity. For BROF aimed shooting (any realistic way to use this weapon at the moment) reloading takes less than 3% of your spent AP. In case of BROF+Fast Shot it's still only 5.5% usage, meaning you would save 1.3%/2.7% of your AP with the upgrade. Nothing else granted. For shooting 100 times, you will save enough AP to fire 1 extra aimed shot, or 2 extra fast shots.
Plasma Pistol (Ext.) -similar story as for ext. Laser Rifle, in case of BROF+Fast Shot reloading takes 6.25% of your AP, changing the saving to 3.125% - that means it will save you AP for only ONE extra shot per ~30 shots (because in this case shooting takes the same amount of AP as reloading).
I am not saying EW should be buffed, however it would be really nice to change those upgrades to be meaningful upgrades. It wouldn't really hurt canon if you care so much about it, because those descriptions can be interpreted in multiple ways in game mechanics - and frankly, recycler chip allowing you to load your rifle more? Not exactly anything that would description suggest.
