Go with Samsung; the diference in price it is like at any other product(car, weapon, fruits,...), it is from quality, specs, availability and brand...some ssd have tlc, others mlc, 3d cell, look for reviews, the cheap ssd tend to mislead with the speed "up to" xxx number, this "up to" it is like at internet ISP bandwidth, can be or can not be, so read reviews, but most agree that today Samsung have a lead in ssd market, have good quality and constant solid high speed on read/write...

some use didferent tech. some ssds have like 3-7k writes some have more like 70-100k writes.
to me personally the higer writes is worth a lot more than speed. in every day use i doubt you would notice a difference between a slow ssd and a fast ssd (when comparing to mechanical drives they are all a lot faster)
