the only TLC i know in market is Samsung 840 Evo and the old 840 only. the PE cycle ranking are as follows

1. SLC - 100k PE cycle
2. MLC - 5-10k cycles
3. TLC - 1k cycle

its already proven that TLC already have the lowest PE cycle and degrades faster than the other two types of NAND. ofc thats all under load work with SSD, if youre not doing any heavy work, TLC NAND can last as long as MLC
AnandTech wrote a damn good article about it as well, read it Understanding TLC NAND

going TLC is certainly a good way for mainstream consumers, as most of them are turned off by the price of the more pricier MLC NAND SSDs. however, the price of TLC NAND (Samsung 840 Evo) is not exactly on the cheap side. Samsung is still pricing it at RM359 which is equivalent to what most standard MLCs cost anyway. given the pricing is an arse, going TLC when other MLC are available at the same price is a pretty silly move

that being said, Samsung Evo is still one of the best and fastest SSDs out there. just that i wouldnt recommend Samsung Evo for heavy users due to TLC and the price range. youll gonna need to swap SSD soon if you keep performing heavy write loads on it. itll reach the PE cycle limit way faster than MLCs
V300 is a decent SSD, but do avoid new batches. AnandTech mentioned that the new batches currently have issues in reliability and consistency (Kingston changed manufacturer from Taiwan to China). So if you notice the V300 batch youre interested in is made in China instead of Taiwan, i suggest getting a different choice as per below

Crucial M500 - reliable in terms of speed and quality, may not be the fastest SSD but still fast enough, have good built in encryption method, power loss protection (for those who have twitchy home power)
Plextor M5S - slightly faster than the M500, cheapest of all at RM289 as per this date, consistent performer as well
Kingston HyperX 3K - fast and reliable, Sandforce controller, top of the line for Kingston SSDs
Intel 530 - fast and reliable, best among all the ones mentioned above, 5 year warranty compared to the 3 above, comes with Intel's superb SSD softwares
Samsung 840 Pro - fastest among all SSDs above, comes with great software support as well, but extremely pricey, 5yr warranty

as per above reasons, i wouldnt recommend Samsung 840 Evo.
