I agree. There are further differences: 2.5in vs M.2 (more pricey), SATA vs NVME (pricer), NVME 3.0 vs 4.0 (pricier), and certain products of a brand are alot more expensive even if the same interface and capacity is used.Today most SSDs are well grouped into ranges. Eg 1TB is between 110 and 140 Eur and saving 10 Eur on questionable manufacturer is under big question.
Also what matters a lot is warranty. Difference between 3 and 5 years is 10 - 20 Eur. Think 5 years worth few Eur more.
Also, DO NOT trust manufacturers and their numbers. There are a lot of sites with benchmarks showing real results. Copying huge files is not real example!
But most important: Google before buy to see what others say!
Question - My laptop requires M.2 2280 SSD. None of the units listed indicated they were 2280 SSDs. Or are they?
That is the most standard size (22mm x80 mm - ratio is about like a stick of gum) and the one used by all the M.2s on the list. Very few are made smaller than that (your laptop would probably accept the smaller ones too as they are just shorter).Question - My laptop requires M.2 2280 SSD.

Horrible list of ssds. Outdated prices, questionable recommendations (Reletech,really?),missing information(ie: m.2 nvme sata or pcie, dramless or not) . You should just take this article down. You started this in October 2020. It is February 2021 now and it says list is updated daily?
US prices are in reality not that much lower than in EU, US stores generally display prices without sales tax, which is only shown at checkout. Conversely in EU all prices must be quoted with tax included at all times.
