3M 6000 series half-face for lightweight applications and the full face one when the integrated eye-protection is desirable. The full face in particularly is undoubtedly bulky, and compared to the one you mentioned, even the half face one is bulky. Filters aren't particularly cheap especially if you want to combine several different filters.... but that's horses for courses, just like the masks themselves. The 3M masks maintain a great seal but I'm sure other brands are equally as good. 3M, GVS and JSP respirators are being widely used in COVID wards but tend to be the disposable ones which require fit testing to determine which shape works best.
