Im using both Viper ultimate and logitech superlight. Still prefer logitech tho. VIper ultimate the click seem something off for me. Not smooth or maybe I got lemon unit.

You must have gotten the V1 optical switches which were known to be "mushy" and scratchy. Razer updated them to the V2 which has a slightly lower g/f, lower tolerance for pre/post travel actuation point, and increased spring back force. They also improved consistency in QC for their v2 optical switches.
Any batch model after #2050 (year 2020, week 50 build) is guaranteed to have a v2 optical switch. All DeathAdder v2 Pro and Basilisk Ultimate also has the v2 optical switch. Razer are now working on their v3 optical switch, which presumably should release with the long-requested Viper Mini Ultimate.
Logitech GPW stock omron 50m switches (D2FCF-K) are just passable. Nothing great. Reliability wise they're either prone to double clicking issues or they're not, so it's a 50/50 thing on that. But in terms of feel, they're no where near as good as the similarly tensioned Kailh GM8.0, which offers much better spring back feel, lower pre/post travel (buttons are snappy), and because of much better QC means the likelihood of double clicks should be lower. Basically switching to GM8.0 makes the GPW the perfect mouse. Stock switches are whatever.
