Well, it really depends on yourself, I guess.
Right now I'm looking at a NIB Encore with brown laminate stocks, stainless, for $575 plus $25 shipping. That's $600.
I also am looking at a NIB blued/camo Encore for $425 plus $13 shipping for a total of $438.
The cheapest Pro Hunter I've seen is a blued one for $650 plus shipping with is $30, the cheapest Endeavor is $800 shipped and running up to $900 plus shipping.
If you compare blued to blued, that's over $200 less. Stainless to stainless, it's $200 to $300 less. Either way, the difference could pay for a blued or a stainless 26" heavy barrel (not a Pro Hunter), or it could put a decent Leupold or Nikon scope on the gun. To me, that's not a small difference.
BUT, and it's big but (LOL), if you have the money to burn and really want to go the Endeavor route, I won't try to change your mind. If people didn't buy the new stuff for whatever reason, then the companies wouldn't have much reason to keep going with R&D of new ideas. If you want it, buy it. For me, after handling (maybe fondling is a better word) both, the differences in the two aren't worth the differences in price.
