Keyboards can be very personal, and what you look for will be vastly different to other people. For example your example looks fucking awful to me. TKL all the way, as the arrow keys on a 75% are mashed in with the other keys so its like some sort of shitty laptop keyboard. My wife refuses to use one that's not full sized as she uses the ten keypad all the time for work.
But since you posted here I assume you care what other people think, so here is my opinion.
You've posted in UK mechanical keyboards and unfortunately this is not ISO, so the layout is missing keys.
If you have your heart set of 75%, them what about a Keychron?
