Unfortunately everyone focuses on the sequential speeds. Outside of a few esoteric tasks (mainly video editing and file encryption and compression), it's the 4k read/write speeds which make the most noticeable speed difference. The reason is simple - the small file 4k speeds are the slowest (typically 30-120 MB/s), so your SSD spends the most time handling them. So they're what bottleneck your SSD.
So ignore the sequential speed benchmarks (unless you're doing video editing or lots of file compression). Get a SSD with fast 4k speeds, and you'll be happy. Aim for a minimum of 30 MB/s 4k reads (queue depth = 1). 70 MB/s 4k writes as a minimum. The 860 EVO typically hits 45 MB/s 4k reads, 120 MB/s 4k writes. If you're severely budget-constrained, try the MX500 - it usually scores about the same or slightly slower.
