Quad-Capture vs. Komplete Audio 6 vs. Propellerheads Balance

Hey Time to "upgrade"! Wich one to choose, there + and - for all of them... but very similars? Your thoughts and experiences are welcome, tia. _ Balance is quiet pricey in regards to the 2 others... and only 2 inputs, no MIDI but AUTO-SENS _ Quad-capture is nice, but only 2 inputs, but with MIDI and AUTO-SENS, good price _ Komplete Audio 6, nice, good price (in between), MIDI, 4 inputs (great!), no AUTO-SENS More?! Anything else? And yes, this is the price range and number of inputs/outputs I'm looking for. TIA. Zouki
