I know how painful it is to shad off their love to wonderwaffe. You are not alone.
First, you don't evaluate tank capability by pitting them against each other. You evaluate tank capability wheather they able to support infantry in battle or not.
Western wonderwaffe (Tanks ) heavily used in many of Ukrainian offence. Unfortunately none has performed as what Brown Sipoy has been telling us from years.
On the Other hand, there are countless occasion where T-90 has performed exceptionally.
No matter how many times a day you repeat death- trap death -trap in a day. T-90 tank so far performing best among Wonderwaffe.
Well sir , I must say that being on a defense forum I certainly know that the " TANK" came into being, specifically to destroy massive trench lines in WW1 , and they were quite successful in their endeavour.
Now let's get to iran iraq war , in 80s, the Iraqi t 62s outperformed the iranian chieftains and m60s ,more than destroyed during the battle of dezful or karun river during the Iraqi operation NASR.
But same Iraqi tanks were sitting ducks when attacked by Abrams and challengers in 1991
Or in 2003
Now if must here say that Iraqis had perfected defensive war against iranians, because after Iraqi advance was stopped in 83 ,from that time till 87
Now In this time period, Iraqis were busy in construction of large sand defenses , I mean extensive ones.
Hence when iran launched operation Ramazan , it failed and after that came a string of iranian offensives like operation beit al moqaddas, operation tariq ol qods, the karbala series of offensives
From karbala one to karbala 8 or9 .
In all this iran , was on offensive, the battle for Basra being a highlight, ( look at the Google maps to see that Iraqi defenses still exist from that era .
) Iraqis were tenacious, and thier artillery, pulverized enemies hordes of children on bomb laden bicycles , teenagers charging at them without a a gun and finally proper troops , tanks here played exactly same part as you mentioned ( support the infantry), as being mobile artillery themselves.
Hiding behind defenses.
Iraqiis finally went on offensives in 87 with their Ramadan Mubarak and tawakal ala allah operation series, which forced iranian side for peace .
Fast forward 1991.
Same tactic was employed, Iraqis were using their tanks for troop support again , yet american Abrams destroyed them in huge numbers with their depleted uranium shells .
What went wrong here ?
What went wrong was that Americans had adequate number of tanks in the field against Iraqis not a couple of those like ukriane has .
Which has no airsupport, left no air defence left etc .
Hence Russian t Boss seem superior to many .
I really don't think I will change my opinion on this issue anytime soon, sir hence let's agree to disagree.
Whatever serves well In our time of need is best for us.
