The Gobi is a jack of all trades. I think of it as a midrange that wants to be a fairway driver.
I love my Gobi for one disc rounds where I need a single disc to fill multiple roles, but I find trouble fitting in my bag for normal rounds, because it doesn't seem to specialize in filling any single role better than other more specialized discs. The first time you hold it in your hand, I think you'll understand what I mean. It calls itself a midrange, but it has a rim that feels like a driver with slightly dulled inside edges. You throw this disc like a driver, and in a lot of ways it behaves similar to any number of slower, more controllable drivers on the market.
The Gobi is a little longer than most mids, even long mids like the Evidence or the Truth. The only mid that really competes with it in this category is the Warship. At some point these mids that keep trying to fly further than their competition just become fairway drivers, and with the Gobi you definitely get the feeling that you don't really need a true defined "driver" on most of the amateur courses you find in the United States since you could easily throw a Gobi on a 300' hole. If you want a driver with a comfy fat rim that won't dig into your fingers, then the Gobi is definitely the disc for you. I'm not trying to bash the Gobi here, and the comfort factor is definitely a big deal because this is one of the nicest discs to hold in your hand and throw repeatedly because the plastic they use on the inside of the disc gives it an incredible comfort and ease of throwing. But if you want a mid that won't overshoot the basket, then the Gobi might be a disappointment in the sense that it flies just a little bit TOO far at times. For true midrange duties, you might want a true midrange.
The Gobi also fits in a kind of weird weird in-between spot in terms of stability. You can definitely shape your shots to get hyzer, straight, and anhyzer flights out of this disc. However, it might not perform as well as more specialized discs for any of these shots. I've noticed that anhyzer shots in particular tend to flex out halfway through the flight unless you put quite a bit of power on the disc, because the Gobi has a fair bit of low speed fade to counterbalance its high speed turn. You'll notice that this tendency to fade more at the end of the flight is actually a defining characteristic of drivers, and to find this level of fade on a midrange really highlights the fact that this disc falls between the "midrange" and "fairway" categories. In a lot of ways, this disc is more similar to a Leopard than it is to a Buzzz. You can get it to hold an anhyzer line if you give it a great deal of anhyzer angle or just throw it hard enough on an anhyzer line, but it's not an easy disc to keep turned over on shorter throws. I recommend Latitude 64's Fuse if you want a mid that will stay turned over on anhyzers without trying to fade back at the end of the flight.
So what does the Gobi do better than its competition? Well, it definitely flies far, especially if you get a nice hyzer flip on it so that its (slight) understability holds it straight and gives it maximum glide. In that way it's quite similar to a Warship. But another, underappreciated advantage of this pseudo-driver like rim is that it's actually really awesome for forehand shots. If you need a midrange that you can forehand comfortably, the Gobi can definitely fill that spot. This disc is among my favorites for forehands inside of 250', because it's just so gosh darned easy to get a clean release with the rounded inside rim on this disc. Give it just a little bit of hyzer and it will flip to flat and then fade predictably so long as you don't torque it over too badly. The extra distance and glide this disc naturally gets will allow you to just flick it gently at the target and let the disc do the work, and I think the Gobi actually fills this niche better than anything else it could be doing for backhand throws. So rather than being a jack of all trades, master of none, I think the Gobi is really a jack of all trades, master of one. It is a very well rounded disc that can fill almost any role decently, but the one thing I found that it is excellent for is forehand approach shots.
On the whole, I wish I could give the Gobi a 4.5/5 because it is so good for so many things, but since the rating system on this site only allows for whole stars I have to give it a 4 because I still have trouble fitting it in my bag for just that one shot where it outperforms other midrange discs. The Gobi is a very versatile disc, and very comfortable too, but finding a place for it in your bag can be tough because it is versatile and when trying to score as well as possible you just want a specialized disc that is perfect for a given situation rather than a versatile disc that is decent for that situation.
