They are both very strong range hoods with 500CFM.
We bought Sakura 747 many years ago from Homedepot with similar price but they don't carry it any more.
The 747 is little bit stronger (580CFM after I checked its spec) than those two listed above.
For me, I'd like to pay more attention to the spec of CFM than other features. If it's over 500, it'll be concidered as powerful, then it shoud be good enough for the Chinese style cooking.
