I think this is a personal thing, and I think you can make a case for either/or. Some of our members are very passionate about one way or the other, as has come up in similar threads.
For myself, I have been ridiculously happy with who I hunted with on my two trips over (
@GAME 4 AFRICA SAFARIS), and I will absolutely hunt with them again, particularly if I get to take people with me who haven't hunted Africa or have minimal hunting experience (and I have a few of them in mind) because I feel 110% confident in the experience they will have, their chances for success, and the level of care and attention they will receive. I am certain others offer great experiences; I cannot imagine anyone else does it better though.
That said, if I allow myself to dream, someday I'll get to pursue species I probably can't find there, so I'll be seeing new places for other types of animals, and the thought of that is exciting too.
And lest I have seem wishy-washy, my thoughts on Africa mirror what I do here in Alaska. I have a number of spots that I love to get back to as often as I can. They feel familiar - they feel like home. In my mind I can't possibly see them enough. At the same time I enjoy seeing new places. Last year it was Sitka for deer, and this year Kodiak for goats.
I guess in my mind if you truly enjoy hunting, and all of the peripheral stuff (stopping to smell the roses)... I don't think there's a wrong answer? Just my two cents, in a really crappy economy.
