Budget bookshelf speakers recommendation - Polk ES15 / Elac Debut B5.2

Hi, everyone. I'm looking for some help deciding between Polk Audio Signature ES15 (220€) and Elac Debut B5.2(200€), both being currently on sale at a local store. They will be powered by Wiim Amp. The combo will be my first setup after years of Edifier Active Speakers. I'm particularly interested in sound quality (good mids and decent bass) at low to medium levels listening.

Thanks în advance for your help!
