Any benefits upgrading to Coffee Lake from Haswell for a non-production box?

Hello Reddit,

My current Hackintosh is a vanilla Mojave i7-4770K/z87 motherboard/16GB RAM/RX 480 GPU/1TB SSD (triple partitions for Win10 and Ubuntu 19.10), which is working fairly well (video acceleration, sleep, audio, network, etc). I have installed a compatible WiFi/Bluetooth adapter so it communicates well with my iPad 6th gen.

I know Coffee Lake Macs support the new Sidecar feature (using an iPad as a secondary monitor), but apart from that, the faster DDR4 RAM, and the higher core/thread counts if I go big enough, is there any real benefit in upgrading? I don't use the Hackintosh for production purposes, I work support in a mostly Windows shop. I know there are plenty of Sidecar alternatives that will work with my Haswell Hackintosh so that is not a killer requirement (I have 9 monitors connected to my main battlestation so I *REALLY* don't care about Sidecar other than as a curiosity). The Hackintosh is not my main battlestation at home so if I blow it up it doesn't affect me much unless I am actually researching a MacOS issue for work.

I only built the Hackintosh because:

• I had the parts lying around.
• I needed to learn MacOS because I got stuck with supporting a few real Macs at my work (used by the graphics, video, and online teaching teams)

Would I really benefit from upgrading (which is coming out of my pocket as work will not pay for it) other than a bit more performance and a bigger hedge against obsolescence? I am still using Mojave because my work uses Adobe Creative Cloud (Photoshop, After Effects, etc.) so I haven't been able to gauge whether going to Catalina will require a better box than what I cobbled together. My work Macs are a mixed lot but at least 1 of them was bought in 2018 so it is quite a bit newer than my own Hackintosh.

Thanks in advance for any advice!
