I recently bought a L6060 and was planning to buy the LP grapple but dealership sold it twice, lol. Glad they did for allowed me to relook at the LP. I bought the EA wicked 60 after taking more time to compare them. To me the LP looked to be a sold unit and I liked the metal on the back side and do think it may offer protection the EA does not. However the LP is made for pulling it backwards to pull roots out, look at the little teeth on the BACK of the bottom. Not a SSQA expert but I believe it is made more for pushing and not pulling. For ripping roots backing up means you may have to drive across them first but at least get the grapple past them. To me, that means either taking short pulls or driving across them. I don't care for either. However backing up would most likely prevent digging too deep with the lower teeth which I can do with the EA pushing it.
I am also able to slide or twist the EA grapple for hooking it up. One thing I don't like on it is the rounded design is not easy to set on the ground upright for unhooking and rehooking. It is round enough it must be braced or will roll forward or backward or does for me. I found best way is to open it fully and lay it face down before disconnecting it. May be looking for a way to add legs to keep it standing but this is not a deal stopper.
It is easy to use the top tines fully open rotate heavy to pull smaller roots and limbs into "wind rows" if you need to but for a serious root remove is done with the lower tines in push mode. It takes paying attention to the depth the grapple is when doing so as easier to be too deep, I don't find the bracing makes it ride out as is suggested in their video. However you should not be pushing at a fast speed anyhow. On my cab L6060 have handle piles of limbs from 1 inch to say 8 inches and logs over 12 inches with it. Do find with a grapple full you need to bump it closed a few times as you are moving as the load does some settling allowing the load to move, issue I have is the curl and 3rd function will not operate at same time but easy to get use to. That is not the grapple design issue, it is Kubota's 3rd function and maybe anyone's 3 rd function issue, not sure.
As to price, the EA for me was maybe $100 more due to buying LP with tractor but to me the LP looks to be well made I would buy the EA hands down again. Have enough belief in it told my baby sister they need to consider the EA for their 3000 JD and she said her neighbor told her the same and he uses one on his did some rock moving for them. She has rocks, we have mud holes...difference in hill land of Texas and low land of South Carolina.
I have no doubt if you decide to buy the LP you will be pleased with it, but believe you will find the EA is better design. Not sure on the LP now but the teeth on the EA do not line up with the top and bottom, that allows them to pass each other to tighten better than the grapples whose teeth do line up with each other. Of course that means you can not pinch a small limb or board between them but it does mean you have tighten on a dozen of them which is more common.
Regardless what grapple you decide on, if working with limbs or such you need a grill cover for your tractor. I considered expanded metal in the back of my EA and talked with them on why they don't offer it and told me it would fill with small debris blocking your view, I agreed with their thoughts and built a grill guard.
