verb book comparison

I have 501 Russian Verbs and The Big Silver Book of Russian Verbs. 501 I borrowed from the library and I bought Big Silver from amazon.
My first impression was to go with 501 because I had used 501 successfully with French, Spanish, and Italian. However, when I looked at the Russian 501, it had a lot less content than the Romance language ones. There are no examples.
I like the headings in the Big Silver book. They are big, bold and easier to read. Another big, bold thing is the TOP 50 VERBS marker on 50 of the 555 pages. I am not sure how they chose the TOP 50 VERBS, but it does get your attention. I don't really care for the serif font used for the main text.
I am glad that I bought the Big Silver book, mostly because it gives lots of examples and usage instructions.
