I have Kemper, FM3 and TMP. To me, the Kemper feels the best (as long as the profile is good). For my own sanity, I have gone back and forth between Kemper and FM3 (using an ABY box) and Kemper always feels/sounds better. Then I got the TMP to try it out. For some amps, TMP sounds as good as FM3 (maybe even better) and for some amps TMP sounds much worse (Vox). I have arrived at a point where I will keep the Kemper and TMP and sell the FM3. I don't need all the amps in FM3. Also, the limited options in TMP get me to playing faster whereas with FM3 i am always tweaking, changing amps etc. TMP reminds me of playing an amp i.e. set it up and play.
