Tripod leg locks

I keep reading differing opinions on leg locks.  It is a matter of taste.  I've used both flip locks and twist locks.  I like both, but I can offer some comments based on my experiences.

Flip locks are fast, and it is easy to see if they are locked or not.  With my old Bogen 3221, I had to keep a tool handy to tighten the screws because they would periodically loosen.  I was unable to use the tripod until I fixed the loose screws.  Also, I have caught branches and such on the flip locks.  I expect that years later, flip locks have improved where the problems I had aren't problems anymore, but it is bound to depend on the design.

When I switched to a carbon fiber Gitzo 3530 years ago, I thought I wouldn't like the twist locks, but I got used to them within a couple of days and haven't given them any thought since.  Speed hasn't been an issue since I can loosen all of the screws on a single leg with a single twist, and re-tighten them similarly once collapsed again.  They have never caught on any branches.  They are easy to clean.  They never need adjustment.  Visually seeing if they are locked or not hasn't been an issue for me; I feel when they are tight or loose.  Also, the Gitzo ALR feature really does work, and I assume most other brands that use twist locks have a similar feature... it helps prevent collapse even if the legs aren't totally tight.
