Just had the same question when buying mine and first of all, check the dimensions because Lenovo usually has 14.5’’ display which is basically 1.5cm of diagonal less than the other one, and possibly you wouldn’t even notice the difference.
Secondly though, the professional I went to for buying my own laptop suggested me a 15.6’’ just because 14’’ tend to heat up very quickly, since they are so small. In this case though, the specs for the second one are significantly better, though idk if I would suggest a Lenovo (found their costumer service practices a lil sketchy, and my sister had one that broke easily).
All in all, for 1000€ I think you could find interesting HP laptops or ASUS ones (especially if you’re not in a rush, with Black Friday coming up), but that’s totally your choice.
In my country, this one fits the budget, is a 2-1 and the specs you’re looking for
