Hm, I guess I'll play. I have (and regularly use):
PT12 - It's fine and super ubiquitous but I have 48 channels of conversion and they want me to pay HOW MUCH to get more than 32? Yeah...no thanks.
Cubase 8 - It's fine, but the whole "only one clip playing at a time on a track" makes me want to have a seizure. I mean, I have to pre-define my punch points when doing overdubs? Meh.
Reaper 5 - I like it. Particularly for multi-track drum editing. It'd give Sonar a serious run for it's money in my joint if it had ARA.
Studio One 3 - I really like it. A lot. It's getting close to supplanting Sonar as my primary DAW. No fully routed and bussed multi-out track templates (super handy for stuff like Superior Drummer), but really good handling of external hardware FX and good multi-track drum editing.
Sonar - What can I say? Look at my forum join date. Couple of nagging issues that are making Studio One really attractive for me right now, but still mostly my go-to.
All of that said, I'm not much of a DAW zealot. Which flavor of DAW I use is one of the least important decisions I make. The whole "DAW X is better than DAW Y" debate has always seemed to me like chefs arguing about which brand of pan to use. I mean, Caphalon vs All-Clad? Meh...I'm just here to make a bourguignon, so pick a pan cause I got a lot of onions to chop.
