I used to get very good results using BioRad agarose for
electrophoresis, Qiagen gel extraction, ligation and transformation. 

The lab I am in now are using GIBCO/BRL ULTRA PURE agarose for 
electrophoresis. My transformation assays have been less efficient 
since I came to this lab.

I am wondering whether others have similar experience with GIBCO's
