Amp-sim feedback - can you hear the difference?

[prabblerabble]

Tracking a song and I keep switching back and forth between three amp plugins, the LE456, TSE x50 Beta, and LePou Legion. I don't know if it's because my ears are exhausted, but I can't which one I like the best/if I can even hear significant differences. Let me know which one sounds best and on how whatever I've tracked so far sounds!
