It isn't the end all be all, and it depends a lot on the specific nvme drive, but it makes a difference. Toms Hardware frequently benchmarks traditional SSDs and NVMes using Final Fantasy XIV game load times as well as PC Mark 8 Storage Tests while using Office, World of Warcraft, & Battlefield 3, so these aren't just purely synthetic benchmarks and often the SSD has several seconds extra for load times and have a fraction of the throughput with real world applications. I know it sounds trivial but when you open a large excel file and it just opens instead of having that little moment of noticeable latency, it is a MUCH better experience. I used to have a 66 mhz 486 processor that predated Intel's Pentium line, so I get how it is borderline insane for me to say that going from a wait of 2 seconds to a fraction of a second is worth it, but I know I'd never go back.For games and most software the difference between a current gen SSD and NVME drive is negligible. way faster than a mechanical drive, but not than each other. it has other advantages like form factor allowing for very compact builds for instance.
