You bringing this up multiple times doesn’t mean I have to automatically agree with it.
The added armour won’t take away the fact that the composites near the gun shield are lessened due to the various mechanisms mounted there.
That weakspot will remain, and even if I didn’t, it’s such an incredibly minor area that it still doesn’t change the overall picture of the SEP v3 being a M1A2 SEP sidegrade.
I’ve got 3400+ kills in various M1’s combined, the number of times I’ve been killed through that area can be counted on one hand.

Improved FLIR was planned for the SEP v4, the SEP v4 ended up being cancelled and portions of it’s planned upgrades were moved to the M1E3 program.
The SEP v3 was retroactively to receive parts of the SEP v4 planned improvements, but I’ve not seen mention of this including the FLIR upgrade.
The Meteorological Sensors were definitely moved to SEP v3, but that component plays no role in War Thunder.

Sorry to be blunt, but those that disagree with me on this topic and those that don’t make use of mobility are consistently players with significantly worse stats.
You achieve around 1.3 kills average per match in your M1’s, that’s pretty awful and I would not be surprised if that’s the result of a player sitting back and cautiously camping from stationary positions for the majority of the match. This highlights exactly why it’s not a meta playstyle, as do your poor winrates in these M1’s.
There’s a reason why every. single. one. of the most skilled players say that mobility is amongst the most important aspects in War Thunder.
Nonsense.
Here’s the Army’s description of the role and tactics which the M1 shall fulfill on the battlefield:
‘‘As the Army’s primary assault weapon system the M1 will satisfy the Main Battle Tank requirements during the 1980s and beyond. Capable of sustained offensive and defensive combat, the tank is designed to close with and destroy the enemy using shock action, firepower, and mobility in coordination with supporting ground and air systems under all battlefield conditions and levels of combat.’’

That argument doesn’t hold water because they already have good all-around mobility, the literal best gun handling characteristics in the game, and still have solid firepower.
If your argument were true and that their armour and survivability is what allows them to be the #1 best MBT’s, then the same would be true for the T-90M. Clearly that isn’t the case because the T-90M is among the worst 12.7’s in the entire game.
The T-90M is just a Strv 122 if you took away the Strv 122’s reverse speed, neutral steering, reload rate and gun depression, that illustrates how much of a difference those factors make.
The HSTV-L is the fastest vehicle at top-tier, and despite it’s MASSIVE drawback in post-penetration damage, it still manages to be excellent due to that ludicrously mobile chassis.
