.shop or .com?

Hi! What domain extension you recommend for dropship store?
NicheShop.com - long, harder to write and remember
Niche.shop - short cool looking, but I don't know what people think about extension they probably never seen before. Do they trust it as same as com? I not talking about .mx , .io, .pw... but .shop for online store.

Anyway both domains with my niche KW are already taken..
So putting ''best" in front of domain is good or bad idea?
BestNicheShop.com
or
BestNiche.shop
