Sansamp Fly Rig 5 vs. Line6 Amplifi FX 100

I am currently looking for a modeling type devise that I can use into my home mixer for personal practice. I also want something small enough to take to gigs as a backup in case something happens to my live rig. I want something that has amp sims and effects to perhaps use when playing small stages. I have done a significant amount of research and have boiled it down to one of these two. The Sansamp (analog) gear seems to have a good reputation but is lacking some of the features that the Line 6 Amplifi FX 100 (digital)has. any advise would be much appreciated!
