I vote lease. First of all hunting isn't just about killing to me. It's about time spent outdoors. You will get far more of that from a lease than an outfitter trip.
And second I just like doing things for myself. I don't care to go somewhere and have a guide lead me out to a stand and point to it and say "sit there". And of course tell me what to shoot as well. To me that's kind of like when your dad used to take you fishing as a little kid. He'd bait your hook; cast the reel; set the hook on a fish; then hand the pole to you so you could reel it in. Fun when I was 5 years old I guess but not as a grown man. I like to do my own scouting; hang my own stands. I like to choose when and where I hunt. And while I do try to shoot mature bucks I also like not having to worry that I will be fined 1000 bucks for shooting a buck that turns out to be 2 inches under some outfitters minimum.
