Does anyone use any of the digital Kenyusha English – Japanese dictionaries? Thinking about getting one but there’s very little info about them regard what they provide over each other.

Been looking on the Monokakido dictionary store (for my Mac/Tablet/iPhone) and there are three, the New English-Japanese Dictionary 5th edition. and 6th edition, and then the English-Japanese Dictionary for the general reader.

Up till now Ive been using Shirabe Jisho as my go to dictionary but I need something that explains the nuance and usages of words better (as Shirabe Jisho doesn't at all) and something with much better example sentences. Willing to drop cash on one as ive been 5 years into studying so I think it'll be a worthy purchase. I just can't seem to find info that differentiates them the best. What does General reader mean? is there any reason I should opt for 6th edition over 5th? are neither suited for my skill level (late n4 just etching into n3 territory)?
