Reply to Reason 6 and such

I have Reason 5 and was wanting to get some feed back on whether or not I should upgrade to Reason 6 or just keep 5. I've been using Ableton 7 but it just doeen't work for me anymore and wanna go back to Reason's work flow. On another note, anyone using Maschine with Reason, have any input on how well they work together? Thanks
