OK, the recommendation would be to wait unless you can get a bargain on the Typhoon in the sales. Yuneec are expected to make some announcements at CES in about two weeks' time which may change your options, and I'd expect to see prices updated in the New Year as well.
The Typhoon H had a fairly bumpy introduction - it went through some big changes when Yuneec got Intel involved, had firmware built from scratch and was a little rushed when it first came on sale. You'll note that people are saying the same about the recent DJI products - it seems to be a symptom of the industry with a lot of innovation going on. In addition, there were some 'dirty tricks' campaigns from a particular competitor, who was caught paying people to claim they had problems with drones they had never even bought.
However, most of that is behind us now. The Typhoon has received good support, with regular firmware updates and new features added. It's maturing into a solid platform. To fly, it's a real pleasure - stable, smooth and easy to control. I'd strongly recommend it for professional use.
I can't say much about DJI - I don't own any of their products. If you're looking at the Inspire 1, it's very definitely an old model, and DJI don't seem to offer much support to owners once they introduce the a new machine. The Inspire 2 is getting a lot of press as it's just been introduced, but all I'm seeing at the moment are very short 'first flight' tests and some pretty uncritical analysis by vloggers who want the hits. It takes a few months before people start identifying how it behaves in real use, and any problem areas. I expect it will also mature into a good platform in time.
Which brings us on to this: drones are not reliable technology or easy to use, whatever the adverts may claim. The technology has only recently got good enough to get them into the air and fly in a predictable manner. It's still pretty cutting edge stuff, and so the kit is often operating right at it's limits. Note that DJI have had to drop the top speed of the Inspire 2 after it turned out their initial claims meant it couldn't take stable video. It also means these things crash and break down. The're not reliable like an Audi, nor as easy to control as a GoPro. You will crash, it will behave unpredictably, it is hard to get good results when your camera is half a mile away and has pretty basic controls.
If your business is going to rely on a drone, you need to be prepared to make repairs, have spares, look out for problems and expect that there will be times when you cannot fly. You must also expect it to have a limited lifespan. So if you're used to promising your customers a report, then going to visit them with your trusty camera you bought ten years ago, you're going to be in for a shock. If you have a little mechanical sympathy and enjoy tinkering, you'll be fine, but if this is business critical, I'd seriously consider how you'd cope with a machine that is in for repair.
You might also want to check up on the legal requirements for commercial drone operators in your area. Here in the UK, if you fly for commercial purposes, you must have the relevant documentation, have passed a training course and usually also have professional indemnity insurance. This also applies if you fly within a reasonable distance of buildings or people, whether or not you're making money at the time.
