I use UltraTax for business so that is the only other software I've even remotely considered using. I would use them as a last resort due to the high price tag and I dont prepare the more complex tax returns. 

I've never given serious thought or even compared others to any degree other than a cursory glance. PS has ALWAYS been perfect for my needs. Plus, I hate change. I agree with IronMan above. I thought last year was an aberration, a toe stub. This year has not started off the best either.....but I will cut them a little slack due to the Tax Reform this year. The support is disappointing for the 2nd straight year. I am not ready to abandon ship yet.......but I feel they need to shore up in certain areas. 

Okay, back to work.
