Our problem with using CFIMPORT is that you can't use a variable in the taglib attribute, which means you can't use a config file to define the location of the custom tags for a specific application. So you're in a jam if you're building a framework that might be used in multiple places on a shared host.
This is because CFIMPORT is a compile-time directive, which also means you can't place it in your Application.cfm; instead, you have to place CFIMPORT directly on each page that calls one of the custom tags in your library. CFMODULE is great for solving this problem, but then you can't build custom tag editors for your custom tags because the tag actually being edited is CFMODULE, not your custom tag. We use the cf_ syntax so that we can use mappings, define the custom tag path in ColdFusion Administrator, and also build custom tag editors for our custom tags. The code produced using cf_ syntax is also much more compact and easier to read. Which brings us back to the whole shared hosting thing, because you can't bind a specific custom tag path defined in ColdFusion Administrator with a specific application, because ColdFusion doesn't have a true concept of an "application" like other platforms do. So now we're back to versioning problems when you have two custom tags with the same name anywhere on the same shared host box: which version does it call? The first one accessed since the last reboot, most likely, since ColdFusion caches the path to the custom tag once it finds it the first time. To solve this problem, we've created a little drag-and-drop utility for the ColdFusion community that enables you to drag your finalized code in your application root over the utility icon, and it creates a safe copy of your codebase with all cf_ syntax converted to CFMODULE syntax using Template="#Application.customtags#" to define the path. You simply define Application.customtags in your application's configuration file, and bada-bing!, no more shared hosting issues. We haven't posted this utility yet, so if anyone needs a copy just contact me offlist.
