Wrapping two queries into one as I must be spamming this forum

Hey all, I've been looking around for info and opinions on Hotone pedals since I am looking into getting the 'Choir' pedal but I could not find anything.
I like the pedal's sound (based on YouTube reviews) but I can't find any opinions about quality etc. Must be fairly new.
Also, would it be better to boost my sound with a Tube Screamer (E.G. Bad Monkey) or would it be better to go for a specifically designed clean boost pedal?
