I can't think of any particular story that I liked more than others. It really depended on my mood. On the other hand, I can't think of ANY of the stories that I flat out didn't like. I will say that I was never fond of any of the Cimerora stuff. I didn't actively dislike it, but I never went out of my way to DO them.
I think the only one that stands out to me that I really enjoyed was the Sara Moore one in the Shard. Something about that just was so much fun. Part of it was just the Shard itself. I always loved it.
To be honest, I never did many TFs. Many times, I just didn't have the uninterrupted time to put into them. I Absolutely HATED speed runs of any TF. I did a few of them and hated every minute of them, until I finally decided I would not accept or would drop from any TF that became a speed run. Also, I started right before I3, and played with very few breaks right up until the shutdown, and in all that time, I have never done a Respec trial on any character. My wife had done the first Respec trial a ton of times in the early days, back when it was common to fail the trial. Once she succeeded and got her character respec'ed, she never ran it again either. Originally, I didn't do it because after seeing all the trouble my wife had with getting a team that could complete it, I didn't want to mess with it. Then I got a free respec for something, probably after one of the issues were released, and didn't need the trial. Afterwards, I always had plenty of free respecs, until the vet rewards came around, and then definitely didn't need to do the trial to get a respec.
I feel kind of bad that I never got around to running it, just to have done it. I mean, I WATCHED it numerous times while my wife had been running it, but that isn't the same as doing it yourself.
