andyskinner - BattleScribe has gone subscription, and for 1 mobile and 1 desktop platform it's $6/year, so it will take 7 years to match the cost of Army Builder - unless they raise the subscription costs which they can at any point. So, cheaper in the short run, more expensive in the long run.
Also, as I understand it, Army Builder's mobile app is just a roster viewer. So, BattleScribe is a win there for flexibility.
To be clear in my view - I need to redo the GF rosters no matter what because 2E is coming out. Once 2E does come out, I am going to have to start from scratch in the current version of whatever program we pick and remake them all; I assume I basically won't be able to use anything. So, since I need to do all that work anyway, I might as well ask what program people prefer. Back when I did them originally, I preferred BattleScribe because it ran on Linux and Army Builder doesn't. I care about that less now that I was able to use the Win 7 license code that came with my laptop to install Win 10 on a VM, so I actually have a Windows machine.
