I'm sure that coming from LOR to LSP it would not seem as user friendly since it is so different, but I started this year with LSP as my first program and felt like I about had it mastered after a few hours. As far as warranty, service, and support, David has done an awesome job responding to my emails and even offered to do a LogMeIn session on an issue I had.
I think most will agree that not only is LSP not catching up, they are leading the industry. The ability to program via layers and transitions is the only way to program RGB in my opinion. LSP's boast is that it can import and export multiple formats as well as work with just about every controller on the market. I feel like the whole philosophy of LSP is about making the software work for you with what you have. I have a friend that uses LOR and a friend that uses Vixen and they both were impressed when I showed them LSP and both stated how much faster and easier I could do complex sequences.
