Never tried the Bushnell, but my Nikon 440 has endured a lot of use and is still going strong.

I am amazed that after 3 years or so, they're still the same price! I got mine on sale for $179 3 years ago and I assumed it was because they were phasing it out for a new model!

One note though: it does not have a "rain mode" so if it's very rainy or foggy you will not get accurate readings (the water droplets refract the lazer). I don't know if the bushnell has a rain mode.
