No direct experience with the Hisense, other than the very cheap sets they make, but I'll chip in with my opinion again. Second-string manufacturers (in general) of high-end TVs can look good on paper, but they fall short on execution. That being said, by all accounts, Hisense have been improving year by year, and may be climbing towards the top rung.
I think that buying a lower-end model of a big name brand is often a better choice than a high-end TV from a smaller brand. The giant corporate machine of the big-name brands leads to a more consistent product.
Edit: Consider the
Samsung Q75R (QA75Q75RAWXXY)
Reports from friends and family and random Whingepoolers, some things to consider if you aren't buying from one of the big name brands:
They may buy their panels and parts whatnot from the big boys, but it is the final product execution that is often lacking.
Quality control (panel uniformity, dead/stuck pixels) and material quality can be lacking. Particularly the remote controls are often terrible.
Out of the box calibration/accuracy is not great.
You often miss out on comprehensive picture adjustment options, and the user interface can be very poor in general.
Their picture enhancement controls (noise removal or motion smoothing) are often very basic, and in some cases undefeatable.
Image processing in general is usually adequate, but not cutting edge. I note that on the linked model, that it has four HDMI-INs, 2xHDMI 2.0 and 2xHMI 1.4-only. No HDMI 2.1, but that is a 2018 TV, so that's understandable.
They often lack any decent app support. While the smart features can be performed by external boxes, and it is sometimes preferable to do it that way, sometimes the only way to get certain formats like Dolby Vision is via an app on the TV itself. (mind you, that model you linked is HDR10 only, so perhaps that point is moot).
Ongoing firmware update support for previous-years models can be limited.
