I think they're similar.
Unfortunately, there's some tradeoffs:
The original brown LGHG2's were AWESOME, but first it became a problem that there were fakes, and then almost a year ago Mooch indicated they weren't testing as well as originally - even legit ones.
The Sammies, I liked the original baby blues, but wasn't as thrilled by the newer green ones.
Still - both are great
batteries.
I also really like the pink Samsung 30Q.
I think if you're buying from a reputable vendor, any of those are great
batteries...I like and use all three...
And I run them in P67's and also my Grand. Maybe it increases the button throw - I don't know, cuz I'm just used to how it fires and I'm happy with it that way!
How noticeble is the useful run time on these compared to the Samsung 25r if you have used the Sammy's?
