My title says it all.
I like the compact size ... pinseeker is too large for me to carry around.
I like its x6 magnification ... tour v2 is compact too but only has x5 mag. Also v2's yardage display is not as clear, big font size, as LR800.
There is no non-sense feature on LR800, such as switching modes (why do I need other modes if I only use this for golfing). I just aim at my target such as pin, bunker, water, etc and the yardage shows up in a second when I press the button. It turns off by itself so that I don't have to worry about anything.
If you are considering Nikon Monarch 800 or Nikon 800s (almost the same as LR800), you can switch between first target priority mode and distance target priority mode with these two models - good feature if you would use this for hunting. LR800 does not let you switch, but I only use this for golfing and do not want to bother switching, it is prefect for me.
I also like the carrying case of LR800. It is really designed for golfing - you clip it onto your bag, open the lens cover, and you are ready to go. Nikon's own 2 models come in a pouch, so you will need to take the rangefinder out and put it back ... it would make me feel like taking a picture on a golf course.
LR1200 is good too, but the size is slightly longer than LR800.
