Dictionary and Encyclopedia Prioritization Questions

I want to prioritize Encyclopedia Britannica Noet Edition as one of my English encyclopedias in my library so if I come across a term not covered in one of my prioritized Bible dictionaries (such as Anchor, etc.), it will fallback to Britannica. 

My question is, should I prioritize both Britannica and Compton's in my library or just Britannica? Any reason to prioritize both?

I also have Collins English Dictionary prioritized as a fallback for looking up English word definitions not covered in Bible dictionaries. Should I also prioritize Webster's (maybe 11th edition) or is there any reason I should or just prioritize Collins?

Thanks!
