Early chapters I'd say Rebirth of the Thief, Nie Yan being a thief and using unconventional tactics to find good grind spots and soloing boss monsters by abusing NPC AI and/or special terrain and using the thief class stealth advantage + special items to do special quests and/or grab higher-level treasures. (Sword God also has a bit of that stuff, but a lot less and usually much more simplistic.)
Unfortunately the author just had to be Mad Snail and he's too full of shit and senile so stuff that happens before constantly gets retconned etc. The novel is/was very promising, but simply being promising doesn't make it good. That just makes it even more disappointing when it turns out to not be what it should have been.
Reincarnation of the Strongest Sword God however, it's definitely worse in the beginning 200-ish chaps (and it doesn't help that it's clearly being a Rebirth of the Thief copycat), but besides that the author can remember at least most of the stuff (or at least he sometimes goes back and look it up whatever crap he wrote before I guess?) and although there's still quite a lot of bullshit and obvious plot holes (like in most webnovels, especially CN ones) at least there's less of it and they usually aren't significant to the plot. (Which can't be said for Rebirth of the Thief unfortunately.)
Something quite unique in Reincarnation of the Strongest Sword God (which some might actually dislike, at least at first—I kind of thought it stupid at first as well, though after reading 2k+ chaps I think it's a good thing) is how instead of one chapter describing what happened in an entire week, what usually happens is that multiple chapters go in depth about everything Shi Feng does in a day. This is shown to the extreme in the beginning when after like 100 chapters it's still the FIRST DAY (which is actually 48 hours in-game, but still) of the game and everyone is still below level 10. I think they didn't even get to the city before 200 chaps?
Also something to note is that in Reincarnation of the Strongest Sword God, a lot of the times when you think the author has completely forgot something and the MC (Shi Feng) is retarded for not doing x or y, you'll find him doing that say 500 chapters later, and it still has only been like a week or two (maybe a month), so a large part of it is just about that.
And as a side "bonus" I guess, even if there's some plot hole or mistake chances are that you'll have forgotten the exact details by the sheer number of chapters in between, making great use of "Fridge Logic". I've personally went back and checked some stuff (and checked wiki too) when I felt like something is up. But while there obviously are plenty of times where the author forgot something or just retconned, I found myself incorrect often enough as well.
Now there definitely are still some timeskips, but usually they're just a day or two, maybe a week tops, as Shi Feng is at some place grinding or doing some special quest in a disconnected location.
In both novels it doesn't help that the MCs just tell everyone to do as they say without explaining anything at all and thus looking like idiots until after the fact. In this aspect I think Sword God is a bit worse than Rebirth of the Thief, though it could be because it's the one I read most recently so I just feel it more strongly.
Anyway, something to keep in mind when reading. Rebirth of the Thief is completed at 995 chapters, Sword God is 2500+ chapters and still going, and at this rate it's going to be like 8k+ chapters. Mainstream players are still level 60+ while MC is level 70+ and MC was level 180+ in his past life after 10 years.
The time is still like around 1 year since the game released, so 9 more years before catching up to his previous life. And it could go on even past the previous...
Btw this is one of (if not the only) novel I can say I could totally see myself reading 10k chapters of, but for many reasons that might not be the case for you, so that's something to keep in mind; maybe you'll find this novel better, but simply by the fact that you'd have to wait for years before it finishes or that you simply don't want to read so many chapters, you might end up preferring Rebirth of the Thief or something else anyway.
