which mx switch is better of typing? clear or brown
Clear is a slightly heavier brown, so it's up to you.
That's not quite right, actually. Clears and browns have different stems. A clear stem has a much larger tactile bump than a brown stem. The ergo clear is a clear stem with a lighter spring, approaching the same weight as a brown spring, however this feels much different from a stock brown. If you look at the stems side by side, you'll also be able to see the difference.
That said, it still is definitely personal preference between browns and clears. My preference is for stock clears, as I prefer heavier and more tactile switches.
