I have both Lightroom and all but one Topaz plug-in. I would say it depends on your needs...that doesn't help much does it, lol! Okay, my new basic editing routine is download raw into lr, do some basic adjustments if needed, then I go to topaz denoise, then detail, then back to lr. After that I save a tiff, and then may play with it some more in some of the other plug ins topaz, etc, depending on where I'm taking the image. For straight images without much or any layers or manipulations, lr may be enough but you can't beat topaz for noise and I really like detail too...and the others but those are my main go tos. LR can do a lot of great processing, watching some tutorials will help get the hang of it. Also, everyone is going to have their own system of editing, that works for them.
