Both had their strong and weak points.
The Browning M1919 was not designed as a 'general purpose' weapon, but rather, a medium machine gun, and thus lacked some of the features of the MG42, such as a design which allowed for it to used to some reasonable degree as a squad level support weapon, if need be. The M1919 always had to be mounted on a tripod during operation, whereas the MG42 had a bipod.
The method of attaching the M1919 to the tripod was much simpler than the same process for the MG42. As for rates of fire, the MG42 had a rate of fire of around 1200 rounds per minute, which was effective at keeping heads down, but also burned through ammunition stocks quickly, and caused rapid barrel overheating, which required the barrel to be changed at regular intervals.
The BAR machine gun is recommended for its accuracy and portability whereas with the browning you sacrifice these qualities for greater fire rate, ammo capacity and bullet penetration. Actually, the Browning Automatic Rifle (aka Browning Machine gun) IS the BAR; they are one and the same. BAR is an acronym for Browning Automatic Rifle.
A comparison is impossible to my way of thinking because the MG42 was a machine gun and the bazooka was a rocket launcher. It is an apples versus oranges contest. The German counterpart to the bazooka would be the panzerschreck, or possibly the panzerfaust. The US counterpart to the MG42 would be the Browning M1919.
The Browning. No Contest there.
The British and American machine guns were no match for the German light machine guns. This is not just an opinion but it is based on facts. Their rate of fire of the German guns were higher. The BAR held only a 20 round clip. The German light MGs were not as heavy. The American Thompson and the British Sten gun were pretty good weapons but still not better than the German MP40 machine pistol. If it wasn't for the American M-1 Garand rifles, the German rifle company would probably have had more fire-power than the American rifle company. Another factor when comparing weapons is their reliability and serviceablity as to how they performed in the field when exposed to water, dirt, sand and mud. The American Model 1911 pistol could withstand much more abuse than the fragile Lugar pistol. That is my opinion.

a machine which is a speed multiplier is the better one
It all depends on what "better" means to you.
The obvious difference between American and German cars are brand names. It is also believe that foreign cars such as German engineered vehicles are of better reliability. Different parts are used for both sets of vehicles and of course there is the matter of cost.
yes, and upgraded mg42 is better than an upgraded browning because the browning still takes longer to reload and mg42 takes about 3 seconds. Browning takes about 7-8 seconds.
The earlier the better. 1 is in the Browning Museum.
In World War 2, no, not necessarily better in terms of quality and performance, but US guns were simpler, and US industry could produce more of them. German factories worked by slave labor had trouble supplying the German Army with enough guns. In comparing the US M1 Garand rifle with the German Gewher 43, the G43 was actually a superior weapon, but the Germans managed to produce them only by the thousand while the US made over a million M1 rifles. In World War 1, both armies were equipped with guns which were roughly equal to each other, with a few exceptions. For example, the US M1911 pistol was much more rugged for trench warfare than the delicate German P-08. Yet, the Germans had much better machine guns than the horrible French Chauchat which US machine gunners were required to use. US Marines did a bit better, equipped with the British Lewis machine gun which was not perfect but much better than the French machine gun.
