Elo does not lie, at 3142 Elo GM Iordachescu is better than even Alireza Firouzja and Nepo based on current rating.
Elo is based on wins and losses, yes it can go up and down based on luck or good day or bad day, but it is true that GM Iordachescu is a 3100+ player, one of the best in the world, who has consistently defeated 3000+ opponents.
In my country, opportunities for GM Iordachescu to play in FIDE rating tourney are very limited as he is a blitz specialist. He can earn an honest wage and live a good life but cannot be travelling in jet aeroplanes around the world like the famous if there are no good blitz prizes.
The internet has enabled Violord to show his strength as a great Violent Lord of chess. In fact, he is under rated online as he does not have the expensive equipments that the top players have.
Violord (Viorel Iordachescu) is a foremost blitz specialist, the top Grandmaster from my country Moldova. He was close to 2700 Rapid FIDE, but tournaments are rare in Moldova and travel costs are high.
He has a blitz rating on Chess.com of 3142, this is better than Wesley So who won the recent Chess.com Global Championship.
He is a very solid player who shines online similar to Hikaru. He beat Nihal Sarin and Daniel Naroditsky in recent matches.
