I've been using Beersmith for a while now since I stopped using Brewtoad.com, and the only thing that I have issue with is that you can't put pictures in it. I like pictures in my brew logs...oh well.

I have not used Beertools, but have been using BeerSmith since just before V2 came out. There is a steep learning curve and a fair amount of information about your setup you need to put in and tweak if you really want it to be useful, but I love BeerSmith. It does everything I could possibly want and keeps getting features added and tweaked.
