There's no real comparison between the 2000 and 2020 elections. For one thing, the litigation was limited to one state (Florida) and there was no question as if if the election process itself was fairly conducted.The 2000 election suffered much litigation of course, but this is nothing like as close and the actual conduct of the election didn't suffer the same issues if anything other than unfounded allegations of voting fraud it probably went as smoothly as ever really.
As I recall it, the crux of the matter was that there was a small number of ballots where it wasn't possible to clearly determine the voter's intention. Gore's side wanted to continue the forensic examination of the ballots, Bush's side argued that if it wasn't clear then they should be considered to be spoiled votes.
In 2020 the Trump team are attempting to throw out legally cast ballots where the voter's intention is clear simply because they voted for Biden instead of Trump.
