Just as you said some of the Select figs like the older ones are more of a statue than action figure since they are lacking in the articulation and has predetermined dynamic pose. The newer selects has better articulation. So if you just want to pose and display, Select would be a better choice specially with the included accessories. And Select have pretty much all the main stream marvel characters so your option of 10-20 figures would be good as long as you keep your collection Select only and not intermingle with Legends then scale wouldnt be a problem but then again its your collection so whatever makes you happy. Any collection no matter how big or small is a "worthy" collection.
