"Not as effortless" and "not as powerful" are on point, but "not as talented" is poor word choice here.
ML has mentioned after Polish Open 2015 that
his level was not as good as Harimoto at the age of 12.
LGL has mentioned before Team World Cup 2018 that
no players of the same age on the CNT had an edge over Harimoto.
Miyazaki has even been more direct and boldly claimed(FWIW) after WTTC 2017 that Harimoto is
"a talent that only comes around 1 time in 100 years."
At the press conference after losing to Harimoto at the All-Japan Championships 2018, Mizutani said he was fortunate to have won so many titles(9 at the time) before Harimoto came along and that his strength was on par with the CNT players.
Harimoto has yet to lose to LYJ in international competitions to this date.
Harimoto has
7 8 career titles out of 11 13 finals(2 out of
1 3 in 2022, 1 out of 2 in 2021, 1 out of 1 in 2020, 1 out of 3 in 2019, 2 out of 2 in 2018, 1 out of 2 in 2017) in senior events.
LYJ has
3 4 career titles (5 if counting T2 Diamond) out of 5 6 7 finals (9 if counting T2 Diamond)(1 out of 1 in 2023, 1 out of
1 2 in 2022, 0 out of 1 in 2021, 2 out of 3 (3 out of 5 if counting T2 Diamond) in 2019) in senior events.
WCQ has
2 4 5 career titles out of 6 8 11 finals(1 out of 3 in 2023, 3 out of
1 3 in 2022, 0 out of 1 in 2021, 1 out of 3 in 2019, 0 out of 1 in 2018) in senior events. Take this with a grain of salt as his previously low world ranking meant he kept running into his teammates.
The last thing is we have to factor in their age:
Harimoto 2003/6/27
LYJ 2001/8/17
WCQ
2000-2/5/11(this one is very controversial)
