Likley feels off simply because of the contrast to soviet squads. Paras are there against 5 man rifles so the extra model offers a lot in means of durability. Also being able to reinforce off invisible pathfinder beacons gives them versatility and makes em feel tougher as you can reinforce even on the front (since the beacons don't cost anything you can have em where you need em)
Compare to SOVIET AG are not durable, they are average. All squads have 7 men (well most anyways) and cons can get up to 6. The other smg elite infantry has armour so in the context of the soviet faction AG guards are actually squishy.
How they stack up against other units in other factions is frankly irrelevant because it's not the units in the other factions that they are competing for pop cap with.
I have no feelings towards AG as I have not tried em in this patch, but a squad that can get 3 lmgs shouldn't be indestructible
AG have the same durability as guards (while being cheaper)
The slightly better durability than Penal while being slight more expensive
They have better durability then conscripts
Only shock have better durability and that is because the have to move to range 10 while AG can fight at mid range.
They are simply not "squishy, especially compared to other infantry of their type and cost" and they are are as viable against tank as Paras are.
