Well, I think it's sad that you're letting your choice be limited by what's available only at one specific site.
Ask around, you'll quickly learn that the big Kenkyusha dics are what anyone into serious translation work uses. They're that much more complete and useful. My Random House WaEi/EiWa gives me 4 translations for the word "love", and translations for the expressions "fall in love", "be in love", "make love". This is 10 lines, half as wide as a page (2 columns). The dictionary has 50,000+ entries. Still, when I look up love in Kenkyusha, there's a LOT more. The dictionary has standard 8.5x11in pages, with text just as small as my smaller dictionary. 3 columns per page. "Love" takes up a full column and then a bit more. A huge number of definitions, including "love and hate", "the love between a husband and child", "a mother's love for her children", "love for one's country", "one's first love", "love at first sight", "love all 0" (tennis term), "fall in love", "for love", "for love or money", "for the love of...", "out of love with", "lord love you", "love me, love my dog", and dozens more I skipped over.
There's just no comparison. Kenkyusha is the one big dictionary you need for reference (well, two, since the WaEi and the EiWa are different volumes

). Combine with a small lookup dic (my random house one is nice), a kanji dic, and some tools on the computer, and you've pretty much got all you need. Kenkyusha has a bunch of scientific and technical translations. My Random-House certainly doesn't have translations for Menispermaceae (not that I use that often ... hehe)...
