Welcome to the addiction!
Those are two different beasts.
1. Les Paul will be only that - a Les Paul with the Les Paul sound. I believe it is substantially heavier and will have that particular sound.
2. JP w/piezo....awesome tonal range, lighter, body contours, will stay in tune much better IMHO, and the piezo makes it another axe all together. I don't believe you can beat that if only comparing the two.
3. I own 3 JP's, so my opinion will be biased and it is so for a reason. The feel of the JP is what sold me more than anything else, the tone and sustain are top notch (as it IS built for JP....and they are all built to his specs) and the best part is in my fourth point....
4. The Customer Service and reputation of EB's Customer Service is simply THE BEST in the business. So much so, the employees of EB and the owner, Sterling Ball (Big Poppa on the forum) post regularly and bend over backwards, sideways, up and down for us.....the customer as well as their endorsed artists.
My opinion and it is only that....you will sincerly enjoy the JP for the reasons stated above. I will not trash the Les Paul as it does have it's place in history, but it does not do, IMHO what the JP can do.
My 2 pennies.
