The best DNA analysis software?

[Jayhong A Chong]

I am currently using Geneworks on the Mac and this is pretty satisfactory,
but I was wondering what other people have tried and liked.  I generally do
restriction analysis, multiple sequence alignments, primer design, and
sequencing projects.  I have used PCgene and GCG, and I have access to Mac,
Intel based PC, and SGI platforms.

Thanks for you input.
