The 4 tiers of preset/template

It occurred to me yesterday that Sonar basically offers 4 different levels of 'preset', each more granular than the first:

1. Project templates
2. Track templates
3. FX Chains
4. FX Presets

I used to use project templates a lot, and tried to use FX presets (although the interface for naming and saving them always felt a bit clunky). But then I found that I wanted to use track templates more than project templates so that I could mix and match pre-configured instruments more easily - e.g. re-use the drum signal flow and plugins from the last album on my new recordings, or to quickly insert 2 tracks of identical rhythm guitars panned left and right.
 
Unfortunately track templates seem to have a few bugs, but the FX chains are a handy compromise for someone like me, who has a bunch of individually configured VSTs on almost every track. I may have to add the tracks manually, but being able to replace hand-crafted FX bins with FX Chains means it's rarely a chore. This also makes life easier when I'm in the final stages of tracking and/or the early stages of mixing (both the same thing to me, basically) and I'm looking to standardise the sound across several songs - I pick the one I like best, save the FX chain as a preset, then load that in to the other project. Much easier than using a track template and trying to move clips over.
 
So, I just thought this was interesting, and wondered if anybody else had any thoughts on it, whether they prefer one type over the other, etc.

thought? i wonder if they're actually related entities, like your granularity implies, or are completely separately developed "objects" that have evolved toward each other?
