IMO Incott G23 deserves an A Tier. Great coating (better than ATK X1, and I have both), very good main and side clicks, good scrool wheel, great performance, nice stock skates, hot-swappable switches, ok web driver... The only downside is the weight, wich, TBH, is not THAT bad since Zaopin Z2 has the same weight and is higher on the tier. Ps: My opinion is based on the G23 non-pro version.
Also: rock solid build. No creaking, no flexing, no rattling, etc.
You need mice that suits your hand size and gripping habits. You had a viper which is a medium to large mice and this is probably why I would say the Inca and X2 CL medium are quite small comparatively and is more suited for medium sized hands. A Rapoo VT7 max will be similar to the viper shape and size, ATK A9 or incott g23v2/V2 pro or Lamzu Maya X will be the mice that fits medium to large hands with all grips(except palm for larger hands).
Practice and shape are most important. GPX clones are a safe place to start, Mchose A7 V2, ATK A9, Incott G23 V2. If you prefer a bit larger but still symmetrical, there are Viper clones, but I've only used one so far, namely the Eweadn S9. If you want larger ergo mice, my current main and favourite is the DeathAdder V3 Pro if you can find it for that much, otherwise if the wire doesn't bother you the regular V3 is the same but cheaper. If you need more buttons and don't mind the weight, Basilisk V3, I tried the G502X but the Basilisk felt better for me.
The G Pro Wireless has the same shape as the Superlight but has 2 extra side buttons for left handed users. So if you don’t need those side buttons you can look into Superlight clones. Incott G23 V2, ATK A9 Pro/Ultra, and MChose A7 are all good choices. Now if you need side buttons on both sides, there are barely any mouse on the market with that. G Pro 2 Lightspeed is the revamped G Pro Wireless so it has those buttons. There’s also the Pulsar X2A, but that’s a very different shape.
Yes these clones are good. If Logitech mouse were the same price then you'd pick Logitech, but these 3 mouse are great value at around half or less. Make sure to get one with PAW3395 or PAW3950 sensors. There are some lower tiers PAW3311 sensor which is worse performing. Weight wise these 3 are slightly lighter than the Superlight 2 (50-59g vs 60g). They have solid optical or mechanical switches and good construction. I would personally pick the Incott G23 V2 which reviewers are saying is the best Superlight clone on the market right now. These Incott, ATK, and Mchose generally make good mouse. Avoid stuff from Attackshark and Ajazz cause they have plenty of QA issues, which ends up making it a coin flip on whether you get a good copy or not.
In general if you are talking about Chinese premium mouse, shape irrespective, it should be the Lamzu thorn or the Maya X. If you want to consider only budget brands then Incott G23 V2(the Ghero pro is my fav tho), Scyrox V6/V8 and Rawm ES21/ER21 pro from my experience are the best especially in terms of general quality, tech, sensor perfoemance and QC. Followed closely by Mchose L7/A7/M7 and VXE mad R variants.
I just bought the Incott G23 V2 and I like it a lot.
