Hi Coldtexan,
No one touched this in a couple of days, so I'm here at least to say "Welcome to the forum". I myself don't really have any experience with the DeLorme Topo software, so I cannot be of help. Hopefully someone else can give you an answer.
Microsoft Streets & Trips has good maps, but it isn't really a topographical program. If you need topo maps, you will likely be better off staying with DeLorme Topo.
