Randstad City (Den Haag) v Smaller City (Apeldoorn/Deventer).

As a young couple (low/mid 20s), we've made the decision of buying an apartment.
The cities we're considering is Den Haag or Apeldoorn/Deventer.
Would also like your opinions on Rotterdam.

What are some general things to know, consider or think about when making a decision on which to choose? Or your personal opinions on the cities.
Budget: Max 300k (Availability shows most 260-300k within price range)

We currently live in Deventer but know Apeldoorn very well. The goal is to eventually (10+ years) to sell the place, depending on where life leads.

Our pro's for Den Haag:
Closer to Belgium (Family there).
Easier access to more restaurant/malls/shops.
More opportunities on job market.
Higher potential value in longterm.
Close to beach.

Apeldoorn/Deventer:
Better/nicer apartments for price range.
Preference for smaller city life than big randstad life.
Cleaner/Cozier feel within the city.
Familiarity with the area.
Center located = ease of access all over NL.
