Brutal DOOM vs Project Brutality?

I've finally decided to mod the original games and probably some fan-made campaigns, so of course I wanted to install Brutal DOOM. While installing it I stumbled upon the info about project brutality (which many say to be a superior version of Brutal DOOM). So I wanted to ask You guys:

1. Which do You prefer and why? 2. Since Brutal DOOM was updated to v21 a couple of months ago how up to date is project brutality?

I probably should play Brutal DOOM and then try out project brutality buuuuut I don't think I have enough time on hand for both of them. Thanks for Your help!
