I am just wondering if they both have the same dimensions since i am looking into a upgrade from my old 2015 tab A 8.0 and i want the best experience since the last 3 years my device has been running IF on the lowest settings possible.
To answer the question in the title, yes, the Samsung Tab S7 and 11-inch iPad Pro are the same dimensions (height). Both are 11 inches.
Similarly, if you’re looking at the larger model from each company, the Tab S7+ and 12.9-inch iPad Pro comes remarkably close in size, with the S7+ coming in at 12.4 in and the Pro at 12.9 in.
The chart posted by @JRC_Adventures offers additional information about each device, and I highly suggest taking a look.
Regarding the question in the body of your topic, either device will run Infinite Flight with little to no issues. It’s more of a question of whether you are an Android or iOS person. Any of these devices will be a step up from your current one, so there are no concerns there.
The S7/S7+ would be your go-to device, then! I don’t personally own one as I am an Apple geek, but I believe @Kirito_77 and @schyllberg have one. I’m sure they wouldn’t mind giving their opinions on the device’s performance with Infinite Flight.
I too have recently switched over to the Tab S7+ recently (my earlier device was a Tab S4) & I am very happy with it. It is a bit heavy to hold while flying (because of the solid aluminum build), but the screen resolution & brightness is very good.
I use the S Pen for controlling & I found that is has helped improve my response time at a crowded airport.
The other advantage I see is that the S Pen comes bundled with the Tab S7, while, I believe that the apple pencil (if you need it) has to be bought separately.
There are many other points for comparison & one could argue either way and there are a lot of Youtube videos on this topic. As @Z-Tube mentioned earlier, it comes down to which eco-system you are comfortable with, IOS or Android. As far as Infinite Flight goes, I’m sure that the performance of either device is more than adequate.
