Sogou vs Microsoft IME, which is better?
Sogou wins on a large dictionary, accurate suggestions and rich skins, but has more online features and limited overseas resources; Microsoft IME is built in with fewer online features and fewer privacy concerns. Prefer the system one for privacy or overseas.
How does Sogou compare with Baidu and iFlytek?
All three are mainstream Chinese IMEs; Sogou is praised for its dictionary and suggestions and a large skin ecosystem, while Baidu and iFlytek have their own voice and ecosystem strengths. Choose by habit and install officially.
Sogou vs Google Gboard?
Gboard is privacy-friendly, low on connectivity and strong across languages, but its Chinese dictionary and localized suggestions trail Sogou; use Sogou for native Chinese and skins, Gboard for privacy and multilingual, and switch by scenario.

Which is better overseas?
The mainland Sogou build can be slow for skins and dictionaries overseas and needs login to sync; if that matters, use the system keyboard or the Sogou international build. For dictionary and suggestions, the official Pinyin build with login still wins.
Is Sogou worth using?
Yes for a large dictionary, accurate selection and rich skins and stickers; the mainland build has overseas resource limits, and for strict privacy the system keyboard is an option, so choose by need.
Should I switch from the system keyboard?
The system keyboard wins on privacy and simplicity; Sogou wins on dictionary, suggestions and personalization. Many people use Sogou daily and switch to the system keyboard for sensitive input.
Is there a lighter alternative?
For something lighter, use the system keyboard or the international build; but a Sogou-level dictionary and suggestions are hard to match. Use the official Sogou Pinyin build and the system keyboard for sensitive input, not unknown trimmed builds.

Will switching IMEs lose my dictionary?
Switching does not touch Sogou local dictionaries; to keep your personal dictionary, export a backup or sign in to sync, so you can restore after switching phones or reinstalling.
