No, it has nothing to do with loyalty but with utility and how you weigh the different feature sets of each browser (speed et al. being features as well for the sake of this discussion). I find such claims disingenuous because they assume that Chrome can act as a drop-in replacement for Firefox which can be trivially shown not to be true. You seem to compare the browsers from the point of shared features or features exclusive to Chrome which understandably can lead to wrong conclusions about Firefox users.
Chrome's features don't constitute a superset of Firefox features and vice versa. Examples for features exclusive to Firefox:
1) Tab groups
2) Awesomebar (which works very differently than the Omnibar)
3) History sync
4) Load tabs on demand
5) Bookmark tags
6) Livemarks
7) Better resource usage (especially memory)
And I could easily add several more, both native as well as the ones added by extensions. You may not care about some or all of these features because they don't fit into your browser usage pattern, but others do. Speed is also important to me and I'm glad that Firefox gets improved with each new version currently but it's not the deciding criteria as long as it doesn't inhibit me from using the browser as I wish.
