Must admit i haven't tried any other than 2, i did 1 a little while back in the day but that was way too primitive. 2 is just right. I did try 6 demo version, it took me 15 minutes to install it, then i spent 30 minutes getting through the settings, and the text is so small that you need a magnifying glass to read it .... then my motivation went away and i scrapped it.
I just stick to 2, it's perfect.
