I would say go for 320d if you can. Basically the same engine and fuel economy is identical to 318d (in some real world tests I’ve actually seen 320d with slightly better economy as it doesn’t need to be driven as hard).
I had a 420d for a year and power was “adequate” for the type of car - if could only afford a 18d engine I’d honestly rather just get a nicer spec non premium car than a slow BMW.
Post LCI has the much improved so in any case go for the B47 some others have said
