Personally, the 2000 mark is the sweet spot for value for me.
You can get very good bikes at the 1000 price point (dollars, euros or pounds). But they are made to a price point and often have very obvious shortcomings: heavy wheels, lower-end groupset (9 or 10 speed) and heavy finishing kit. As people get into riding, those are things that they will often want to upgrade.
At the 2000 price point, you arent getting as many corners cut. You may have lower end groupsets, but that will be mainly slightly higher weight - you still get 11 speed, which is good for long term compatibility. The wheels are likely a little better as well. So all in all, you have a bike where there is a much lower impetus to upgrade.
