I've been through a fair few sequencers.
 
Of course Sonar is the greatest sequencer in the world .
Now I've got that out the way 
 
I've noticed recently how much I really like geist, I think this is my favourite sequencer right now.
 
Before I was using Maschine, and believe me, Maschine sucks, I've read all the manuals and the main problem is patterns always loop in scenes come what may. Also it's a nightmare importing/exporting to Sonar. So I had to dump it until NI do a better job, it's really sad because it has so much potential.. Of course if you loopy loop all day you will probably never notice..
 
What are others real opinions? What is your fav sequencer?
 
Cheers..

Geist is definitely my favorite sequencer if you're talking about sampler/drum machine sequencers. Although I have a couple of niggles with it (hopefully to be addressed in the upcoming Geist 2), I'm constantly amazed at how well designed and user friendly it is. It's almost become like a second DAW inside of my Sonar projects. I make a real pig of myself with it, sometimes having 3 instances of it each with all 8 engines full. 

My favorite is the two-channel, ten-step sequencer permanently attached to the ends of my arms.

They're called bitflippers for a reason!

This is like those surveys every year to see which is the best DAW software. It all depends on who shows up to vote, not necessarily which is really the best in terms of functions. They all seem pretty much the same to me but maybe I'm missing something. I like the way Sonar Platinum works for me.

Do the bits flip in 1s or 2s compliment?

There really is no one best sequencer or DAW. It depends on how you use it.

Project5 is the best sequencer!! 

I use FL Studio and Geist within Sonar.
 
I don't do much sequencing or midi stuff in Sonar, just does not work well with me so I Rewire or use a plugin within Sonar.  or import into Sonar from another DAW.
 
Reason, Maschine, FL Studio, Geist for the sequencing.

I love my Yamaha QY700!!
