Michael Lopp decided to move away from Things:

How can I trust that I’m using the state of the art in productivity systems when I’m using an application that took over two years to land sync I could easily use? What other innovations are they struggling to land in the application? Why hasn’t the artwork changed in forever? What is that smell? That smell is stagnation.

Daniel Jalkut responds:

He applauds the app for allowing him to do his work “frictionlessly.” How does a software developer achieve this level of performance? By first building a quality product and then working deliberately over months and years to address the minor issues that remain. Woodworking makes a reasonable analogy: after a chair has been carved and assembled the job is functionally complete. It’s a chair, you can sit in it. It’s done. But customers will gripe with good cause about its crudeness unless the hard work of detailing, sanding, and lacquering are carried out. Only then will it be considered finely crafted.

I’ve gone through a similar process several times in the past few years. Why change something that works? But, on the other hand, why avoid trying something that could be better?
