It is not a tougher player pool, the grading systems are very different - and both are very different from FIDE.
To get to 2100 in any of them is excellent though. I keep trying to touch the 2000 bar here but it is slightly too high
Santoy_UK, Thanks! And good luck with your goal too.
BroiledRat, Thanks!!
Today I reached 2200 blitz!!
