Flipper
I have a flipper, and while it's probably the best magnet cleaner I've ever had, it still takes a lot longer to use than a regular scraper (like Kent). With the kent, I don't get wet either, but probably keep drier. When you pull the flipper out of the water, it's soaking wet (the spongy scrubber side at least). I wouldn't leave it in there in between cleanings.
A kent scraper, you just go up and down, you can control the pressure and speed, you can knock sand off the blade easily if you need, pull it out of the water real quick to feel the blade for anything caught on it. I guess the only downside is you might keep hitting your light fixture.
I've been using both the kent scraper and flipper. Kent scraper for the overflow walls, but flipper for the rest... though I feel like the flipper is more work.
