I have a F-5C that may help with the premium booster to clarify, and I get around 1-2 kills per mission. For tanks, I tipically play in the BR of 6.7-8.3, and get around 1-4 kills per mission, and also have a T54E1 that I ocassionally use.
The US’s best aircraft at top tier is the F-15E currently. with the F-15C a decent second best.
Don’t even bother. Gaijin doesn’t give a flying F about balancing the US. All of the M1A1s and newer are under armored, bugged, and improperly modeled. Both the HSTVL and RDFLT are missing 100mm of penetration. Claws’ (the spaa) radar works half the time. The aim 120c7s are complete shit and underrepresented in the game (that leaves you with 4x aim 9xs which are decent). Since you are planning on doing GRB, the F-15 and F-16s are both very underwhelming since the maps are smaller and doesn’t make use of the aim-120s. The Aim 9ms are one of the worst close range IR missiles and AGM-65s are trash. You’re better off going with Russia or Germany if you want to actually have fun.
I don’t have it yet but the F-18 late is the best plane in the US tech tree.
Germany = very nicely armored MBTS and the Puma armed with Spikes are very deadly vs helicopters and vs tanks on larger maps. They have one of the best helicopters (fire and forget AGMs), one of the best maneuverable fighter jets, and the best SPAA
Russia = Fast small profile MBTs which soak up badly placed shots thanks to it’s era (slow reverse speed as a tradeoff) the best air to ground planes, helicopters are decent, and the best single target spaa
All the 11.7 Abrams, especially the AIM
Worst secondhand car dealer ever
Germany uses the very same top tier IRs and ARHs as USA, with sole exception being MiG-29G with R-73s and 27ER.
Also skill issue, 9M is good. Its terrible dogfight missile sure but its IRCCM works miles better than FoV gate for mid and long range shots (at least when it comes to IRs).
Ony german top tier with working hull armor is the 2A7V, every other can be easily penned with much older rounds. This means they have to rely on fighting hulldown - and there their protection is not that much different to DU Abrams tanks.
Which have since appeared on other helicopters, some that are arguably better due to being able to defend themselves at close range.
For tanks:
Spoiler
M1A1 is a very decent choice. Got good speed, a decent round, and generally a good all rounder. M1A2 As well, Though its a bit slower but gets a better shell. (Only gen 1 thermals for both tho)
If you want better snipers with thermals, go with the seps.
HC and Aim are also about on par with the m1a1 but with there own quirks.
HSTVL is currently the best light tank. Though it doesn’t get that many rounds for what it is. Still good if you know how to use it though.
Adats and claws for spaa. Adats to take out any close-mid range aircraft/munitions/ Claws for long range.
(of course, this all comes with you knowing your opponents weak points and how well you can use your tanks. The abrams is very crew skill reliant, so if you havn’t upgraded them, play a whole lotta matches in arcade. I think it gives the most crew skill. If you don’t, you will be at a disadvantage in almost every fight)
For planes:

In Ground Battles:
Eh, f16C with the 6 agm’s is still decent. Climb high, make sure to notch/flare. And target mid-long range sams.
Haven’t used the 15E that much but its also a solid option if your want to carpet bomb a moderate sized area with glide bombs.
In Air: F15C if you still wanna dogfight decently, F15E for long range. And f18C for more of a middle ground.
For ARB:
F-15E > F-15C >>> F-16C > F-18C
Abrams is the 2nd best MBT series in the game having great rounds, meta reloads and mobility.
HSTVL is the 2nd best light tank in the game, especially for its BR, and is at this point entirely accurate.
I wouldn’t bother with the M1A1 HC line if you’re strapped for time.
I personally like the F-18C over other top jets in America.
