I really think this isn't a suitable question, could you reduce the lvls? (too many and too broad) or improve the question with your actual goal? it's not the same gameplay after lvl 300, this question neither takes into account quest access, charm points, a goal in skills nor takes into account the difficulty/availability/requirements of respawns
There are videos of people reaching lvl 100 in 1 day, or making 6kk exp at lvl 200, while in a new server ppl who invest tons of dollars can't get lvl 100 in 1 day cuz they lack skills/access to hunts etc, so your question is at least for me, half baked and will only lead to fully wrong/biased answers.
