I can get for my new system Kingston SA2000M8/1000G or Gigabyte GP-GSM2NE3100TNTD
Both are the same price, both come with 5 years warranty

Just need to know which is better overall, which is more reliable in your opinion?

I'm confused.
Which is better for everyday tasks and gaming and reliability?
The gigabyte comes with better performence 2500MB/s | 2100MB/s
but you say that the kingston is better for long term?

NOTE: The gigabyte m.2 card seems to be "NVME 1.3"

The A2000's controller, the SM2263, is generally superior for load times and general usage than the Gigabyte's E13T. That is typical for SMI controllers especially as they tend to be paired with Micron flash. The rated sequential performance isn't really relevant. The A2000 also has DRAM while the Gigabyte does not, which can be impactful on general performance/usage. Whether or not this difference is significant is up to the user, but there's a clear winner here in my opinion...

I would opt for the Gigabyte as it is 5 years or 1600TBW, while the Kingston is 5 years or 600TBW. The warranty for each is the lesser of the two.

The Gigabyte also has much better random 4K performance, which is what most desktop users experience the most, although you might not be able to actually tell the difference. ;)
 
A2000: SM2263 + 96L TLC (Micron), Gigabyte is E13T + Toshiba TLC. So the A2000 has DRAM and arguably better flash. The main difference with the A2000 is that it has a large, dynamic SLC cache, which is very flexible, but less consistent than what you'd likely find in the Gigabyte drive.

The A2000 is absolutely better, DRAM plus a controller known for the best consumer performance, I have it a category (or half-category) above the E13T drives like the Gigabyte on my SSD buying guides for a reason. Large, dynamic SLC can be finicky, on the other hand the E13T relies on HMB (using some system memory for DRAM caching) which is also less reliable in my opinion, so they're both budget-oriented options.

If they were the same price and I was buying one drive for primary, I would personally go with the A2000, if those are you only two options.

Ha, yeah, TBW doesn't mean much for consumer drives.

I'd wager money that Micron flash would survive more writes, anyway - floating gate is more robust than charge trap in this case. Although Micron is moving to a form of TCAT, nevertheless BiCS is pretty much at the bottom.

Reliability is a different discussion. TBW doesn't really factor in because it's only for warranty purposes, you likely won't write enough for flash endurance to matter anyway. Although I'd give the edge to Micron (A2000) flash all else being equal since it uses a more robust technology (in simplified terms). You're more likely to have a failure with something else on the drive, in which case both have aspects that can be finicky: the A2000's large SLC cache can be inconsistent while the Gigabyte relies on system memory for some of its caching which is more susceptible to power loss, for example.

Phison’s DRAMless E13T isn’t as good as the DRAM based Silicon Motion SM2263EN on the Kingston A2000. DRAMless designs wear out faster than DRAM based architectures, regardless of warranty and are less responsive. That E13T based gigabyte is a tier below the Kingston. And as Maxx said, rated endurance has low overall value when most consumers will only write up to 100TB within 5 years. - I speculate usually 30-75TB. But once the time runs out, the manufacturers not longer are responsible. It’s a marketing tactic more than anything.
