I dislike any Omron switch atm. If you ask me mouse switches overall (not only Omrons) are very low quality products.
I also think that current generations are really worse. Back in the days, the Omrons in the IME 3.0 were very good. Even the switches in the MX518 generation were better than todays omrons.
Buy a lot of 10 omrons and try to find 2pcs that feel the same way.... Good luck.
