Yes, 800mm HEAT warhead is worse than 532mm APFSDS.
Even though LOS of HEAT is 800mm, which is better than 3BM46’s ~600mm, it doesn’t take into account ERA spaced armour, and composite armour that reduces CE effectiveness.
However, you can shoot 4x of these HEAT warheads at the enemy at any single moment, whereas T-80Us can only shoot one of their 3BM46 every 6s.
Of course, it’s better to have 3BM46 shot off initially than a couple HEAT ATGMs, but if you miss / don’t do enough damage / don’t penetrate with 3BM46, you are screwed for 6s seconds unless you reverse / get into cover before they retaliate.
However, 4x HEAT ATGMs is better in that regard.
It really depends on how close you are.
~200m+ and the offset isn’t that problematic. Besides, you can usually track and barrel them and then kill them with OP anyways:
And if you are closer than 200m then why aren’t you taking out their barrel and tracks with APDS… and then going to their side?
30mm APDS can also dismantle the barrel and tracks of any tank relatively quickly, allowing you to kill MBTs frontally with said APDS relatively easily (against targets like the Abrams, Leclerc, Type 10, Type 90, and TKX), or with ATGMs of course.
Side-shots are much more consistent with BMPT because you can spray until they die. You can kill multiple targets in one go unlike with 6s reload 3BM46.
You can also kill almost any vehicle in one-shot due to overpressure regardless of how much they expose their tank, unlike with 3BM46:
Spoiler
Abrams:
Leo 2A5 / 2A6 / 2PL / 2A7V(A lot more difficult than Abrams but still possible. Would recommend going for breech):
If you see 2A4 / 2A6 / 2PL hull, easy overpressure or crew wipe out with HEAT jet:
Chally 2 is a bit easier:
TKX / Type 10 really easy, as well as Type 90:
ZTZ99s are easy too:
Ariete is a bit harder to overpressure (only the gunner optics) but you can just pen it anywhere anyways…
Leclerc is a bit less consistent but still overpressurable even when not exposing its hull / turret:
Can penetrate it relatively everywhere on the turret anyways… including the breech area which allows for ammo detonation.
Merkava Mk.4s used to be invincible to overpressure spam but LMUR addition nerfed their roof armour:
Much tougher cookie to crack than the rest of them but still prone to BMPT shenanigans.
2A7 HU and the Strvs are basically impossible to overpressure though… the only vehicles that are immune to ATGM one-shot spam when being hull / turret -down.
BMPT, on the other hand, is immune to everything when hull-down (and turret-down of course), and can stay hull-down for a large portion of its vehicle. The superstructure is massive:
T-80U:
