Yeah Sims 2 is probably the best one overall.
4 does have more options now, especially for building and create-a-sim. But 2 is better gameplay wise, although you can improve 4 quite a bit with mods. 4 looks better than 2, but not by that much, in fact 2 holds up much better graphically than 3. Of course 4 (and 3) has the best lewd mods though.

And in Sims 4 we had to wait for expansions to have things like swimming pools and a terrain tool
