Should I buy TLOU1 from epic store and it's reliability.

Should I buy TLOU1 from epic store and it's reliability.

As title says I am new to gaming and missed the steam summer sale but epic still has tlou1 on sale rn, but my questions are:-

1. Should I wait for steam autumn sale or is epic reliable coz the first thing I saw an subreddit with nearly 1/3rd the size of this hating on it(won't name coz it has ciss words and i dont risk getting flagged/ban)
2. Will the game be different from others like if I buy from steam say as I have heard that optimizations and other stuff are different(maybe for other games)
3. Lastly and more importantly what is DRM scenario here like is it some you are just buying a license or copy bullshit as I will not buy then or will it considered my own full property irrespective of epic/steam accounts and launchers.
