Can somebody please point out the differences with a customized FuzzyFinder?

As I have it I get fuzzy completion from the root folder, opening splits with <c-j> and <c-k>, opening tabs with the file with <c-l>, deleting buffers from the list with <c-]>, and such.

Is there any difference or improvement one should try? Genuine question, I am really curious. It would be great to see a comparative between FuzzyFinder, Command-T and Ctrl-P...

ps: fuzz config is like this in vimrc:

    " Fuzzy Finder
    nnoremap <leader>fr :FufRenewCache<CR>
    nnoremap <leader>ff :FufFile **/<CR>
    nnoremap <leader>ff :FufFile **/<CR>
    nnoremap <leader>fg ye :FufFile **/<C-r>"<CR>
    vnoremap <leader>fg y :FufFile **/<C-r>"<CR>
    nnoremap <leader>fb :FufBuffer<CR>
    nnoremap <leader>fd :FufDirWithCurrentBufferDir<CR>
    nnoremap <leader>fl :FufLine<CR>

(Ignore the maps, thats how I like it)

Edit: I would like to point out that I have skimmed several times through the docs of Fuzzy Finder and there are several options I dont even use/grasp, so more knowledge and tips on Fuzzy Finder would be appreciated also
