I truly believe that who you use as a guide will have a dramatic impact on your success, followed by where. Both are pivotal to sustained, consistent and high level of success. Some animals to a lesser extent, leopard is not one of those animals as you can easily ascertain from the responses thus far.
A couple/few folks have suggested
@DALTON & YORK SAFARIS which I will wholeheartedly say the same. York was specifically mentioned and he loves hunting cats, but honestly, every one of their PHs loves hunting leopard and do very well for D&Y clients.
I have not personally hunted a leopard yet, but have hunted with them and think the world of their outfit, their PHs, camps, and the concessions they have. Dalton does most of the business side of initial correspondence and bookings, but also is often afield as a PH, so he can prove slow at times in responding, but its not for lack of interest, he is just wearing a couple hats and will get back to you.
When I hunted with them in April this year, a new friend of mine was hunting with York and we shared camp for just over 10 days. That was his 10th leopard hunt with York, and he took his 8th leopard on that hunt. What's crazy is he took it on their first sit, and barely 1.5 hours into that initial sit. Part of that is York's experience in waiting to have a proper sense of the pattern on the very old, big and battle worn tom before trying to build the blind. I think part of it may also be Matt's devotion and luck with hunting cats. As a pair, they are a leopard and lion hunting dynamic duo...but even with that, it is still hunting and they have also struck out twice out of those 10 leopard hunts.
I was excited to possibly lay hands on his leopard and figured it would totally spark a real interest and desire for one, since thus far, I haven't felt it yet. Partly because I do not like sitting blings...well, maybe mostly. Matt offered me to sit with him anytime or every time, but we were doing long days hunting elephant, and there was no way I would want to join and have my accidental cough or any kind of noise, potentially impair his success. I was simply happy to lay hands on it if/when he got it and partake in the festivities of the party after. I didn't have to wait long either.
As luck will have it, I will apparently do a bit of leopard hunting this October when I return. Still hunting a Zim elephant, but leopard is on the list now as well. Yes, in October. Word of advice from a non-leopard hunter....if you want to have a successful leopard hunt...also maybe try to do it during the time of year that helps your chances, not hinders it. October is basically the worst time of year outside the middle of the rains to hunt leopard. For me, it was the situation and opportunity that presented, so I am rolling with it. Fortunately, there is really zero pressure in the hunt in regards to the leopard itself. It will prove a wonderful bonus or icing on the cake if you will. Besides, as I often tell myself when I'm about to undertake something difficult, which I may make even harder....if you are doing something difficult, no sense in trying to make it easy on yourself. (unsound logic)
