Differences between Farm Mania and Farm Frenzy

I'm currently addicted to the Farm Mania series. lol Recently, I won a contest where I got Farm Mania and Farm Mania 2 for free so I decided to try them out and I'm pleasantly surprised by how much I like them. Although I love Ranch Rush-still need to get Ranch Rush 2 at some point -I've never played any farming type games. Well, I do play Farmville on Facebook but I don't count that. lol

Anyway, I'm thinking of trying out the Farm Frenzy series and I'd like to hear what others think about it and how it compares to the Farm Mania series. Is one series better over the other? I'm curious to hear others' thoughts and opinions.
