i bought this and the jar, and this is far better.
it has good fbw, pretty nice systems, awesome cabins, kinda meh mcdu, but really good!
meanwhile jar doesn't fly like an airbus at all with horrible fbw and its buggy af, tho it does have doors, better exterior, better system depth (minus the fbw) and more detail in the mcdu.
my biggest problem with the rw a330 (this one) is that it doesn't have opening doors or hatches, and some of the liveries have missing winglet colors, but otherwise, my favorite now.
