I love my strobe tuners!
I have an old Conn ST11 strobe tuner that works perfectly. I got it as an educational toy, and sort of a nerd-appeal vintage analog curio. However, in playing with it, I found that it gave me perspective on the way notes play out over time, and that's had some spin off benefits. I eventually got a Petersen clip-on. Yes, it's a bit more expensive but it's lasting perfectly with daily use (unlike my Snark which has some bad LEDs now).
The way the strobe display varies instantaneously with subtle pitch variation is useful and informative. For other types of electronic tuner, the response time is noticeably slower and less sensitive.
I've seen some complaints that the Petersen clip-on is difficult in a noisy environment and I can see why. Once it's on my headstock, mine is sensitive enough to detect the notes from another guitar in the room or even voices. However, if I start to tune, it immediately responds to that and doesn't get confused.
