I'm very happy with ARK11.  I can get it to you, if it's not in SIMTEL.
The size saved is usually at least half of the space previously used.

ARC is not as efficient as ARK.  I found that it's faster. (Assembly coded)
Both are basically compatible I think.  

I believe I have a version of ZIP for CP/M too, but haven't tried it yet.  
Actually just found it after searching for a while thru my collection.
ZIP099 ??   Is there something newer or has someone used this?

That is an UNZIP-only program.  There are no ZIP programs that I
know of.  If there are any, I'm fiercely interested.
