What is the difference between esx and QB.

Akame1981,
Hi i used only esx, but is QB worth trying and what is the difference between the two frameworks?

We are using QBCore, used to be on ESX before, but decided to try this.

First of all, in my opinion QB runs more smoothly, but that also might be because we bought better hardware, but personally I like qb better than ESX, does not seem to be as much DB coding, and seems more optimized from the get go.
