The keystone tool alone is worth the upgrade!
Finally, I have something positive to report. I have been using CO 6 Pro to edit my photos taken at recent central European trip. Needless to say there are many cathedrals or building with towers or spires. The typical images taken with a wide angle lens at a not perpendicular angel become distorted. The buildings are falling backward and spires are collapsing to the middle.
The keystone tool is perfect for this! It is not automatic but it is fairly easy to use. With the KS stool, there is no need for the tilt and shift lens, at least for me right now.
The KS adjustment itself is rather quick. Afterwards, going to the crop tab and cropping the KS adjusted image can cause the CO 6 Pro pause while 4 CPUs are running at 100%. I do not understand why it would need 4 CPUs 100% of the time to just crop the KS adjusted photo. I have an Open CL compatible Radeon HD 5550 video card with 1GB memory on order. Hopefully, it can solve the CPU maxed problem.
The CO 6.0 Pro cannot correct the distortion caused by the Canon 15 f/2.8 Fisheye lens. The built-in generic lens correction profile is insufficient. The pillars are still curved, for example. For that, one still needs the DxO Pro or the cheap Hemi PhotoShop plug-in which corrects the vertical curvature but not horizontal.

I haven't used keystone tool as I have the Express version, but I do use PTLens to correct for both true lens distortions and also vertical/horizontal perspective. I have found that if correcting perspective it is essential to have the lens distortions corrected also as even lenses with some distortion (much less than the different mapping of a fisheye lens) will make those distortions appear even worse. Two reasons, one is the distortions will be exaggerated as the part of the image is stretched and the other is that when you have what should be parallel lines is is easier for the eye/mind to see curvature between them vs. when they were at angles before. 0
